Common Questions

How do I know which filters my home needs?

Start by identifying the make and model of your MVHR/HRV unit. These systems are usually installed in a utility room, storage cupboard, plant cupboard, or loft space. The brand and model code are typically printed on the front or side of the unit, or listed in the user manual provided at installation.

Once you know the brand/model, you can browse our range and select the compatible filters. Many manufacturers also list filter part numbers in their manuals.

If you’re unsure, we recommend comparing the dimensions of your existing filters with the product description. And if you still need help, just contact us we’re happy to advise.
