Growlink Climalink Replacement Filters

Protecting Sensor Accuracy with Growlink ClimaLink Replacement Filters

The Growlink ClimaLink Replacement Filters ship as a two-pack matched to the airflow profile the ClimaLink was factory-calibrated against. The sensor uses an aspirated design that draws room air across its temperature, humidity, light, and optional CO2 elements. Filter resistance is part of that calibration. Substitute filters, damaged filters, or filters loaded with dust shift the airflow rate. That shift pushes the temperature reading off the ±0.18°F (±0.1°C) accuracy the sensor was rated for. Over a full run, the drift becomes the gap between a 1.2 kPa VPD setpoint and what the room is actually delivering.

Harvest-Cycle Swap Routine for the ClimaLink Climate Sensor Filter

Most growers swap both filters at the end of every harvest as part of teardown. Two filters per pack cover one ClimaLink and a spare, or two aspirated sensor filter slots mounted at canopy in the same room. The change takes under a minute. Pop the filter housing, drop in a fresh element, snap it shut. Pair this ClimaLink sensor filter set with a periodic visual check during defoliation. Catch a contaminated filter before drift looks like a real climate shift. A clean ClimaLink filter holds the calibrated airflow rate where the sensor expects it. Most rooms work through two filters a year on back-to-back harvest cycles.

Key Features

• Calibrated Airflow Match: Filter resistance is set to the same profile used during ClimaLink factory calibration.
• Two Filters Per Pack: Enough for one full sensor swap and a spare, or two ClimaLink units in the same room.
• Protects ±0.18°F Accuracy: Keeps the aspirated airflow rate stable so temperature, humidity, and VPD readings stay on spec.
• Harvest-Cycle Swap: Standard maintenance cadence — replace at the end of each run, not on a quarterly clock.
• Tool-Free Replacement: Filter housing pops open by hand; the element drops in and snaps closed in under a minute.
