Awesome filter for allergens and dust
Just love these filters. I use to use a different brand until my asthma and allergy clinic suggested these. Now this is all that I buy!

Beware of the size!
Bought this filter (1085) from Lowes for years and about a year ago they changed the manufacturing. This filter is NOT 1" but 13/16" and now is loose in the filter bracket on the unit allowing air to go past the filter defeating the purpose of a filter. Funny how the more expensive (1200) filter is still manufactured the same way and fits perfectly. Beware!
