It is the only thing between a 335's evaporator coil and whatever the room throws off. Leaf dust, perlite grit, spent media, spores. MERV 13 is the densest grade Quest builds for this chassis. The EPA puts it at 50 percent or better capture from 0.3 to 1 micron, the range spores travel in. From 3 to 10 microns, where visible dust sits, it rises to 90 percent. Quest's own framing is that the grade runs 20 percent more effective than MERV 11 and 65 percent more than MERV 8. The payoff is a coil that stays clean and a unit that holds its rated capacity instead of fighting a loaded face. A dehumidifier working through clogged media pulls the same power for fewer pints.\u003c\/p\u003e\n\u003ch2\u003eQuest 335 Filter Size, Change Timing, and the Anden Panel It Resembles\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eQuest publishes this filter for the 335 at unit part 4042500, the 335 277V at 4042600 and the 375 50-Hz at 4046200-NC. One panel per unit. The measurement reads the same 20 x 22 x 2 off the Quest catalog or off a tape measure. It is the only filter in this line where those two agree. Match on the part number anyway, because Anden's DH35813 shares those three numbers and will not fit a 335. On timing, Quest's 335 manual says to check the filter every six months and change it at least that often. For agriculture it goes further and calls for a change with every grow cycle. That also keeps spores from riding a dirty panel into the next crop. That is the honest trade with MERV 13. The density that keeps spores off the coil is the same density that fills up sooner than a coarser grade would. The manual is blunt about the other end of it too. Running the unit without a filter, or with a less effective one, can clog the heat exchange coils. Quest states that it also invalidates the warranty.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuest part 4042545-01:\u003c\/strong\u003e The part number to match for a single panel, which is how these are stocked\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV 13 pleated media:\u003c\/strong\u003e EPA puts the grade at 50 percent or better from 0.3 to 1 micron and 90 percent from 3 to 10, so spores and fine dust stop at the panel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeeps the evaporator coil clean:\u003c\/strong\u003e Quest's manual warns that a clogged coil can need disassembly to clean, which is the repair this panel exists to prevent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolds rated capacity:\u003c\/strong\u003e A loaded filter makes the unit draw the same power for fewer pints, so a fresh panel is the simplest way to keep output where it should be\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits the 335 chassis:\u003c\/strong\u003e Quest publishes the 335 at unit part 4042500, the 335 277V at 4042600 and the 375 50-Hz at 4046200-NC, one panel each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 x 22 x 2, catalog and tape agree:\u003c\/strong\u003e The only filter in this Quest line with no gap between the nominal and actual figures, though catalogs sometimes flip it to 22 x 20 x 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot the Anden DH35813:\u003c\/strong\u003e That panel carries the same three numbers in a different frame for a different unit, and the two do not swap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix-month check and change:\u003c\/strong\u003e Quest's 335 manual sets both at six months, and calls for a change with every grow cycle in agriculture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

Everything the unit breathes goes through it first. Leaf litter, perlite dust, spent media, spores. The EPA holds MERV 11 to 65 percent or better capture from 1 to 3 microns and 85 percent from 3 to 10. That covers most of what a flowering room actually throws off. Quest catalogues the panel as 16 x 20 x 2. A tape across it reads 19.5 x 15.5 x 1.75. Both are correct, since nominal rounds to the frame opening. Keeping it fresh is an airflow question.

Generation matters more than the pint rating here. Quest sold a Dual 155, 205 and 225, then a Next Gen carrying the same pint numbers on a different chassis. The Next Gen takes an 18 x 18 x 2 MERV 13, part 4042787, which will not seat in a Dual. Read the part number off the data plate before matching on pints. Quest's manual for this family says the filter should be checked every six months and changed at least that often. For agriculture it says to change with every grow cycle. The honest limit is grade. MERV 11 lets more of the sub-micron fraction through than the MERV 13 that fits the same slot, part 4039391.

Quest's own wording on the media is that MERV 13 runs 20 percent more effective than MERV 11 and 65 percent more than MERV 8. The EPA holds the grade to 50 percent or better capture from 0.3 to 1 micron. That is the band mold spores travel in.

The number 4032270 is also what they use for the Dual 105, so read the number off the data plate rather than trusting one listing. The 100 makes the timing easy. It carries a filter reset button that trips after 2,000 hours of fan operation. Press and hold it once the new panel is seated. Quest's manual sets a check every six months and a change at least that often. For agriculture it calls for a change with every grow cycle. One limit worth naming.

Both describe one panel. The EPA holds MERV 13 to 50 percent or better capture from 0.3 to 1 micron, then 90 percent from 3 to 10. Spores sit in that lowest band. Keeping the face clean is what stops the machine drawing full power for fewer pints. The 70's manual treats the filter as routine maintenance rather than a spare part.

Its manual calls for the filter to be checked every three months, not six. It recommends replacing the panel every three to six months. Every other Quest family here runs a six-month check. The 70 moves its air through less media, so the face loads faster. Quest's warning is blunt. Running the unit without a filter, or with a less effective one, may cause internal damage and invalidate the warranty. The same panel travels under other Therma-Stor brands, which is why searches for the Santa Fe or Broan-NuTone MERV 13 land here. Match on 4037724 and the brand on the box stops mattering. Bare part-number searches are common on this one. Worth keeping 4037724 somewhere findable, taped inside the service panel if nothing else.

Quest does not carry this pre-filter in their accessory index. Their own Quest 70 manual describes the MERV 13 media filter without mentioning a pre-filter at all.

It matches the MERV 13 panel's own measured size exactly, which is what you would expect from a layer sharing the same slot. There is also no published MERV rating on this part, and there should not be. A pre-filter is not graded media. The HGC prefix on the part number means it reaches the market through Hydrofarm rather than Quest's own parts channel. On timing, the 70's manual puts the main filter on a three-month check.

It is the most penetrating particle size, the hardest diameter for media to trap. The EPA makes the same point about HEPA media. Particles both larger and smaller than 0.3 micron are captured with greater efficiency than that.

Pull the ducting, run the unit on high speed, and judge the airflow. Replace the pre-filter first. Change the HEPA only if the airflow has not recovered. Done that way the expensive panel lasts as long as it should, because the inexpensive one ahead of it is absorbing the debris. Quest also lists an optional carbon and potassium permanganate filter, part 4031878, for gaseous contaminants. That one installs in place of the pleated pre-filter rather than alongside it.

One panel, one unit, no cross-compatibility to work out. Quest's own description is that the MERV 10 media captures harmful particulates from the air. It protects both the space and the internal components of the dehumidifier. On the ASHRAE scale the grade sits between two Quest publishes elsewhere. MERV 8 is held to 20 percent or better from 1 to 3 microns and 70 percent from 3 to 10. MERV 11 is held to 65 and 85 across the same bands. MERV 10 falls in that gap, which is a sensible place for a machine that gets moved into rooms rather than mounted above one.\u003c\/p\u003e\n\u003ch2\u003eQuest Hi-E Dry 140 Filter, and Why a Portable Loads Differently\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe Hi-E Dry 140 is the only unit Quest lists this against, under part 4045100-30. It is also the only portable in this group of filters. That changes how the media loads. An overhead unit lives above a canopy in one room and sees a fairly steady dust profile. A portable gets wheeled into whichever room needs it, often the one being turned over, which is the dustiest moment in the cycle. Check it on the way in rather than on a calendar. Quest does not publish a replacement interval for this filter, and rather than borrow one from another Quest family we have left that figure off. The same panel also sells under the Phoenix name, another Therma-Stor brand, so matching on 4038558 is the reliable route.

Folding the media multiplies the face area inside the same frame, so the panel holds far more debris before back pressure climbs. On the compatibility question we will not invent an answer.

A Next Gen 155, 205 or 225 carries the same pint rating on a different chassis and takes an 18 x 18 x 2 instead. Two limits worth knowing before making the swap. Quest does not list this MERV 13 for the Hi-E Dry 120 or Hi-E Dry 195. The MERV 11 panel in the same size does cover them.

Mold spores travel in that lowest band, which is the reason the grade matters in a flowering room rather than an office. What the panels protect is the evaporator coil. A clean coil keeps the machine pulling its rated pints, while a loaded face makes it draw full power for fewer. Quest's manual for this family calls for the filter to be checked every six months, and changed at least with every grow cycle. Two panels per machine, several machines on a site, and that adds up to a real number of filters across a year.

For a room full of plants that is about the right place to be. The EPA holds the grade to 65 percent or better capture from 1 to 3 microns, and 85 percent from 3 to 10. That is the leaf dust, the trimmed material and the fine grit that comes off growing media. What the panel is really protecting is the coil behind it.

That is where leaf dust and media grit live. Anden builds it as a multi-pleat, folding the media so more surface fits inside the frame. What it protects is the evaporator coil, and a clean coil is a machine still making its rated pints.

A movable one gets wheeled into whichever room needs it. That is usually the room being turned over, which is the dustiest moment in the whole cycle.

The EPA holds that grade to 65 percent or better capture from 1 to 3 microns, and 85 percent from 3 to 10.

That is the fraction a grow room throws about: leaf dust, trimmed material, grit off the media. Anden builds it as a multi-pleat, folding the media to get more surface into a small frame. What sits behind it is the evaporator coil. Keeping that face clean is the difference between a machine holding its rated pints and one working harder for fewer. Anden's timing advice runs across their whole line, and it suits a grower better than most.

Anden folds the media into a multi-pleat. That puts more surface inside the frame than a flat panel carries, so it holds more before airflow drops off. The coil behind it is the reason the panel is there at all. A clean coil keeps the machine at its rated pints rather than drawing full power for fewer. Anden's published interval for the whole line is every 12 weeks or at the end of a harvest.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnden part 5701:\u003c\/strong\u003e The number to match for a single panel, which is how these are stocked\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e14 x 19 x 1, confirmed twice:\u003c\/strong\u003e Anden's accessory listing and the A130 manual's service parts list give the same size and part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot the A130F panel:\u003c\/strong\u003e The movable A130F takes part 5769 at 16 x 19 x 1; the shared 19 is what makes the pair easy to confuse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV 11 multi-pleat media:\u003c\/strong\u003e EPA holds the grade to 65 percent or better from 1 to 3 microns and 85 percent from 3 to 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteady room, steady interval:\u003c\/strong\u003e A fixed unit sees one room's dust profile, which makes the change interval easier to plan than on a movable machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeeps the coil clean:\u003c\/strong\u003e A loaded face makes the unit draw full power for fewer pints, so fresh media is the simplest way to hold output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEvery 12 weeks or every harvest:\u003c\/strong\u003e Anden's published interval, tied to the grow cycle rather than to a calendar quarter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eAnden part number\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5701\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFiltration grade\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMERV 11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMedia type\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMulti-pleat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eSize\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e14 x 19 x 1 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFilters per unit\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCompatible models\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAnden A130 (fixed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eOften confused with\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAnden 5769, 16 x 19 x 1, for the movable A130F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eReplacement interval\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eEvery 12 weeks or at the end of a harvest (Anden)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"text-align: justify;\"\u003eMore on how Quest and Anden size their filters, what the MERV numbers mean and when each brand says to change them: \u003ca href=\"\/blogs\/grow-room-dehumidification\/quest-and-anden-filters-sizes-ratings-and-replacement-timing\"\u003eQuest and Anden Filters: Sizes, Ratings and Replacement Timing\u003c\/a\u003e.\u003c\/p\u003e","brand":"Anden \/ Aprilaire","offers":[{"title":"Default Title","offer_id":47410725355734,"sku":"DH35701","price":32.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Anden_5701_Replacement_Filter_for_Anden_Dehumidifier_Model_A130_box_1050_x_1050.webp?v=1775762043"},{"product_id":"anden-replacement-merv-11-air-filter","title":"Anden 5717 MERV 11 Replacement Filter for Anden A200V1, A300V1, A300V3","description":"\u003ch2\u003eThe Anden 5717 Filter, and the One Spec Anden Does Not Publish\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThis panel covers three machines: the A200V1, the A300V1 and the A300V3.

On a room served by a 710 pint machine, the coil behind that panel is not something anybody wants to be taking apart. Anden's guidance is a fresh filter every 12 weeks or at the end of a harvest. On a unit this size that is the least expensive maintenance it will ever ask for.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnden part 5852:\u003c\/strong\u003e The number to match for a single panel, which is how these are stocked\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e29.5 x 31.5 x 1.75 as Anden publishes it:\u003c\/strong\u003e Their own figure, and none of it rounds to a standard HVAC size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe largest panel in the range:\u003c\/strong\u003e Roughly ten times the face area of the A70's filter, for the largest machine Anden builds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade to fit, not a shelf size:\u003c\/strong\u003e A nominal 30 x 32 x 2 from a hardware aisle is a different part; match on 5852 instead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV 11 multi-pleat media:\u003c\/strong\u003e EPA holds the grade to 65 percent or better from 1 to 3 microns and 85 percent from 3 to 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCovers both A710 builds:\u003c\/strong\u003e The A710V1 and the A710V3 take the same panel, so the V number does not change what you need\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeeps the coil clean:\u003c\/strong\u003e A loaded face makes the unit draw full power for fewer pints, and a coil this size is a job nobody wants\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEvery 12 weeks or every harvest:\u003c\/strong\u003e Anden's published interval, tied to the grow cycle rather than to a calendar quarter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eAnden part number\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5852\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFiltration grade\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMERV 11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMedia type\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMulti-pleat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eSize\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e29.5 x 31.5 x 1.75 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFilters per unit\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCompatible models\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAnden A710V1, Anden A710V3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eReplacement interval\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eEvery 12 weeks or at the end of a harvest (Anden)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"text-align: justify;\"\u003eMore on how Quest and Anden size their filters, what the MERV numbers mean and when each brand says to change them: \u003ca href=\"\/blogs\/grow-room-dehumidification\/quest-and-anden-filters-sizes-ratings-and-replacement-timing\"\u003eQuest and Anden Filters: Sizes, Ratings and Replacement Timing\u003c\/a\u003e.\u003c\/p\u003e","brand":"Anden \/ Aprilaire","offers":[{"title":"Default Title","offer_id":47410725781718,"sku":"5852","price":60.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Anden_5701_Replacement_Filter_for_Anden_Dehumidifier_Model_A130_box_1050_x_1050.webp?v=1775762043"},{"product_id":"anden-merv-11-replacement-filter-for-anden-dehumidifier-models-a100-and-a100f","title":"Anden 5895 MERV 11 Replacement Filter for Anden A100, A100F - 11.88 x 13.5 x 1","description":"\u003ch2\u003eOne Anden Filter for Both the A100 and the A100F\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eAnden's other fixed-and-movable pairs take different filters.

The EPA holds MERV 11 to 65 percent or better capture from 1 to 3 microns, and 85 percent from 3 to 10. That band is where leaf dust, trimmed material and the grit off growing media sit. Anden builds the panel as a multi-pleat, folding the media so more surface fits inside the frame. That is what lets it hold a cycle of room dust before airflow starts to drop. Behind it is the evaporator coil, and keeping that face clean is what keeps the machine pulling its rated pints. One thing to watch on the movable A100F. It meets its dustiest air in whichever room is being turned over, so the calendar is a weaker guide there than the grow cycle. Anden's interval covers both cases.
