Honeywell stopped making this model filter a number of years ago. Instead of a broad range of different size filters, they switched to a design that allowed for the sale of one filter size (height) that could be stacked with a gasket in between them. This made it simpler for retailers to stock filters that would fit lots of different models, and for consumers to find the filters as well. I'd prefer to use the original filter as it was designed for my air cleaner in the first place if it's still available for purchase. After a considerable amount of searching on the web, I found this listing on Amazon for a Honeywell branded filter, the same model that came with my air cleaner. Now, you might say "But I thought you said they stopped making it?" Well, that's true, but as with lots of discontinued products, sometimes new "old stock" inventory is available for many years after production stops. Savvy suppliers see the value in stocking up and selling the product for years...

Replacement HEPA Filter 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 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.

Alert--does not fit in the unit it claims to fit 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.
