This filter is for four Enviracare Models (51500, 61500, 11520, and 17200). I replace my HEPA filter every year because I am very allergic to cigarette smoke, pollens, dust, molds, and other allergens and irritants. Honeywell suggests that you replace your HEPA filter every 1-3 years. Also, this HEPA filter has pre-filters which wrap around it, so you may want to order a box of those, too. Honeywell recommends that the pre-filters be changed every 3 months, but I've found if I vacuum them at least once a month, I can keep them longer. I really like my HEPA filters because they remove so much dust and pet hair from the air. 7 of 7 people found the following review helpful: By Michela (Seattle, WA, USA) - See all my reviews This review is from: Honeywell 21500 Enviracaire True HEPA Filter (Kitchen) Before ordering a replacement HEPA filter for your Honeywell (or other brand) Air Cleaner, be sure to check the model number on the unit.

This review is from: Honeywell 21500 Enviracaire True HEPA Filter (Kitchen) I have a 50150 model and it says right on the label attached to the bottom of it to buy replacement filter 21500.
On the the box that this came in it says it will fit 50150 but this filter was not tall enough for my unit. It was too much trouble to send it back so I ripped the rubber off the top of the old filter and attached it with silicone to this new one. That was enough to get it to fit but I should not have to do that for a 50+ dollar filter. I don't know if this is a one-off problem but I do see I'm the only one with this problem to post a review. |
