OEM-matched MERV-13 air filter for Leizig R32 dehumidifiers — tool-free replacement.
The Leizig MERV-13 Replacement Filter (SKU 31800034) is the manufacturer-specified high-efficiency filter for the LG195, LG228, and LG335 R32 dehumidifier units. Pleated media construction, drop-in fit, no tools required.
The Leizig MERV-13 filter is the manufacturer-matched replacement media for the LG195, LG228, and LG335 R32 dehumidifier series. These three units cover the entry-to-large commercial range in the Leizig lineup — 195, 228, and 335 pints of moisture removal per day respectively — and all three use the same MERV-13 filter form factor addressed by this SKU.
MERV-13 is the higher-efficiency filter tier available for these units. At this rating, the pleated media captures more than 90% of airborne particles in the 1–3 micron range — including many bacteria and fine smoke particulate — and more than 85% of particles in the 3–10 micron range, which covers dust, pollen, and mold spores. For licensed cultivation facilities where air quality directly affects crop health and compliance inspections, running the MERV-13 tier (vs. the base MERV-8) is the defensible choice.
Dehumidifiers in an active flower room or propagation space are continuously cycling high volumes of canopy-level air. The LG228 moves 520 CFM; the LG335 pushes 900 CFM. At those airflow rates, a degraded or undersized filter isn't just an air quality issue — it's an equipment reliability issue. Particulate loading on the evaporator coil restricts heat transfer, reduces dehumidification efficiency, and can shorten compressor service life.
Industry guidance for cannabis HVAC consistently points to MERV-13 or higher as the minimum for controlled environment cultivation, where mold spores and bacterial contamination are active crop risks. Running the correct OEM-spec filter ensures the Leizig unit's internal components stay clean, the rated pints-per-kWh efficiency is maintained, and the unit continues to operate within the parameters Leizig engineered it for.
Filter swap is tool-free — no fasteners, no panels to remove. Leizig's filter access is designed for quick field service, which matters in a multi-unit facility where maintenance rounds need to be efficient. The manufacturer recommends inspecting the filter every 30–60 days. Actual replacement frequency will depend on canopy size, ambient particulate load, and how aggressively the room is managed for dust and debris.
In high-production facilities running the LG335 at near-continuous duty cycles, a 30-day inspection cadence is a reasonable baseline during harvest and post-harvest clean-out periods when airborne particulate is highest. Stock at least one spare filter per unit on-site to avoid deferred maintenance when a filter reaches end of service life mid-cycle.
This filter (SKU 31800034) is specified for the Leizig R32 dehumidifier models LG195, LG228, and LG335. It is not cross-listed for the larger LG508 or LG880 units, which use a different filter size. Confirm your unit model number before ordering — the model designation is on the data plate on the unit's exterior panel.

No. SKU 31800034 is specified for the LG195, LG228, and LG335 only. The LG508 and LG880 are larger units with a different filter size. Check your unit's model plate and confirm the model number before ordering.
Leizig recommends inspecting the filter every 30–60 days. In high-particulate environments — active canopy, post-harvest cleanout, high-traffic facilities — plan for inspections on the shorter end of that range and replace when the media shows visible loading or when static pressure across the unit increases noticeably.
MERV-13 captures significantly more fine particulate than MERV-8 — including particles in the 1–3 micron range where bacteria and fine mold spores fall. For licensed cannabis and hemp facilities where contamination control is a compliance and crop-quality concern, the MERV-13 tier is the appropriate choice. The trade-off is slightly higher static pressure, but the Leizig units are rated to handle it.
No. The Leizig LG195, LG228, and LG335 are designed for tool-free filter access. The existing description and Leizig's own documentation confirm no tools are required — the filter slides or snaps into position without fasteners.
