Recom 4RT Filters

Yes, ordering two to four Recom filter sets at once to cover a full year's replacement schedule is a common option, and multi-set orders are typically priced lower per filter than single purchases. It also means you're never caught without a spare when a replacement is due.

We accept exchanges or returns on unused, originally packaged Recom filters that don't match your unit, at no cost to you. To avoid this altogether, send us your model code or the measured filter dimensions before ordering and we'll confirm the right match.

We recommend the standard 3–6 month interval, checked more frequently during the first months after installation to establish how your specific environment affects filter loading speed.

Recom units are generally compatible with the standard M5/F7 filter combination used across most European MVHR systems, tested to ISO 16890 filtration classes. Original and house brand options are both cut to the same tolerances for a precise fit.

There are two reliable ways to identify the correct filter for your Recom unit:

• The model code on Recom's front cover label — the quickest option
• Measuring the extract and supply filter dimensions directly, if the label isn't legible

Both methods are supported through our size and model search filters.
