HRV and ERV filters for your condo.
Use the ventilator’s model and filter part number, then confirm the dimensions and media. Its specified foam pad or other filter may differ from the filter in your condo heat pump or fan coil. Similar dimensions do not establish compatibility.
HRV and ERV: what changes?
A heat recovery ventilator (HRV) exchanges stale indoor air for outdoor air while transferring heat between the separate air streams. An energy recovery ventilator (ERV) also transfers moisture through its recovery core. The filter catches particles; the core performs the energy exchange. A filter is not the same thing as the core.
Read the manufacturer’s explanation of heat and moisture transfer: RenewAire: how ERVs work.
There is no universal “ERV pad.”
| What you may find | What to check before ordering |
|---|---|
| Foam pad | Exact width, height, thickness, foam specification and model compatibility. Wash only when the manufacturer explicitly allows it, and follow its drying instructions. |
| Wire-supported or synthetic pad | Frame, density, thickness and specified media. Do not substitute foam just because the dimensions match. |
| Pleated filter | Model-approved part number and rating. Some ventilators offer a higher-efficiency outdoor-air filter as an accessory; it is not universal. |
| Recovery core | A separate component with its own care instructions. Never apply a filter-washing method to the core without checking the manual. |
For example, the RenewAire SL75 offers an optional MERV 13 outdoor-air filter. Its specified parts should not be generalized to other ERVs.
Order by model and part number.
Look for the ventilator make and model and the filter part number, then confirm dimensions and media. Heat pump and fan coil filters are listed separately from dedicated ventilation media to help you select the correct replacement.
To ask for an ERV foam pad, send your building address, equipment make and model, any filter part number, and measured width × height × thickness. Mention whether you need one pad or a matched set. A photo of the existing filter can help during follow-up.
Clean or replace?
Use the instructions for your exact model. Some media is reusable; some is disposable. Inspection frequency and cleaning methods vary. As one model-family example, RenewAire’s residential guide calls for filter checks every three months and replacement as needed; it also says its core must not be washed. Do not apply that core instruction to every manufacturer.

Need help identifying the media?
Search your building. If its size is not recorded, leave an inquiry with the ventilator model and measurements.
