Buying Guide: What Quality Looks Like
Keep these points in mind before you buy.
Signs of a quality filter
A sealed frame, labeled HEPA grade, real carbon weight and a clear fit list are signs of a well-made filter.
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.
