Buying Guide: Home Purifier Filters
Keep these points in mind before you buy.
Match the model number
Every purifier uses its own filter shape. Find the model on the label and match the filter part number before ordering.
True HEPA vs. HEPA-type
True HEPA captures at least 99.97% of 0.3-micron particles, the size that is hardest to catch. Pollen, dust mite debris and pet dander are larger, so a true HEPA filter traps them well. Avoid vague HEPA-type claims.
Carbon is for odors, not pollen
Activated carbon adsorbs smoke, cooking and pet odors. It does little for pollen or dander, so do not pay extra for carbon if odors are not a problem.
When to replace filters
Most HEPA filters last about 6–12 months; pre-filters and carbon layers need attention more often. Heavy pollen seasons, pets and 24/7 use shorten filter life.
Home Filter Tips
Change filters the easy way:
- Unplug first.
- Note airflow arrows.
- Seat it firmly.
- Reset the indicator.
