What to know before you buy
Genuine versus compatible filters
Third-party 'compatible' filters can cost half as much as the brand's own, and for many popular models the good ones perform well. The risks are inconsistent HEPA quality and poor fit that lets air bypass the filter. We flag where a compatible filter is a sensible saving and where it's worth paying for the genuine part.
Buy in multipacks and set a reminder
Filters are a repeat purchase, so multipacks usually lower the per-filter cost, and a calendar reminder beats waiting until the air smells stale. Running a purifier with a clogged filter makes it work harder for less clean air — the filter schedule is part of owning one.
Frequently asked questions
Can I wash and reuse a HEPA filter?
Generally no. Unless the manufacturer specifically labels a filter as washable, rinsing a True HEPA filter damages the fibers and ruins its efficiency. Washable pre-filters (the coarse outer layer that catches hair and large dust) are different — those you can and should rinse. The main HEPA filter is a replace-not-wash part.
