Customer Reviews

smaller, cheaper, and works great!
I got 2 of these to use with my Hooneywell enviracaire 11520 the other day and they work great! It is awesome since they're less than 1/2 the price of the 21500 (and the 22500 I was using this for the 17400), so though I was buying the 2 HRF-14s to replace one 21500 HEPA filter, I still saved about 10 bucks!

HRF-14 is Honeywell's new Universal replacement true HEPA filter. The box contains one true HEPA fileter and one foam gasket (I just throw this away since it isn't needed for the 11520). The chart on the insert indicates that it fits the following models of air purifiers (number of filters required follows model number): 11520 (2), 12520 (2), 13520 (3), 17200 (2), 18159 (2), 17400 (2), 50150 (2), 50200 (2), 50250 (3), 50300 (4), 50310 (4). Some of these setups also use the included foam gaskets to pad the filters to the right size, (but you never need more gaskets than filters so you don't need to worry about that when purchasing).

Useage is really easy. you stack them up, putting the gasket(s) on top as needed, wrap them with the prefilters just as you do with the old filters. Then you close up the air purifier and are breathing clean air once again!

Replacement policy is the same as it was for the non-universal filters... The HEPA filter should remain effective 3-5 years for light usage, 2-3 years for normal and 1 year for heavy usage.

Satisfaction probably depends on the number required
I am currently of the opinion that people who do not have to use the enclosed, foam spacer will be happier using these stacking filters that those of us who have to use one (or two). The first reviewer states in his (excellent) review that his machine uses two of these and no spacer. My Honeywell Environcare 50250 uses three and one spacer. When these stacking filters need replacing, I am going to order the one piece replacement filter noted on the bottom of my 50250, filter 24000.

As a requirement of design, there is less HEPA material in three stacked filters then a solid HEPA one. The foam spacer(s) also means some machines will have even less HEPA material for air to go through than the HEPA filter that originally came with the machine: air sucked through the foam is _not_ cleaned, before expelled back into the room, the way air that goes through the HEPA material is.

Rounding to the closest dollar, my machine requires $60. worth of these stacking replacement filters if purchased through Amazon with free shipping. This is less than the one piece, 24000 costs from vendors who sell through Amazon. Via an A9 web search for the 24000 replacement filter, however, I discovered that it can be purchased from a few places for a few dollars less than the three HRF-14s my machine requires, including S/H ($58. rounded off).

If anyone else uses a Honeywell air cleaner that can use stacking replacement filters in a room with a wood stove, opt for the one piece replacement filter size noted under your machine if you will have to use a spacer or two. Mine is used in a room with a wood stove and that seemingly insignificant 1" thickness of spacer surprisingly did make a negative difference in the air expelled compared with the HEPA filter that came with the machine (a 24000 filter).

Need to buy multiple!
Beware, you need at least two, and most air cleaners require 3 of these. And when stacked they aren't as effcient as a large single filter. But if you can't find the larger single replacement filter these will do.
