great to breathe freely again.  Hunter air purifier really helps with sinus congestion.  Filter arrived quickly and well packaged.

The filter fits perfectly, it was easy to install, and it filters junk out of the air with HEPA quality and awesomeness. FYI, for maximum efficacy, do a little dusting of the inside of your HEPA unit before installation to remove all the dust in the pre-filter area.

These fit my Idylis perfectly.  I don't know for sure if these are HEPA certified or not, but with the lower cost they seem to do the job.  Part of the lower cost is that the plastic casing of th Idylis filters has been replaced in this model by cardboard.  This substitution didn't affect the fit, but was a little flimsier for insertion into the air purifier.  My purifier takes two of these filters, but didn't have a problem as the item's depiction clearly indicates that there's only one filter in each package.

I purchased this air filter as a replacement for one just like it. I had the other one for several years but it started making some pretty loud noises and I had a feeling it was on its last leg. I like that you don't have to replace the HEPA filter. I do take a vacuum cleaner to it from time to time and wash out the foam filter. Having cats, it really helps with their dander and also with pollen. Not to mention, I can't sleep without the sound of it running.

We replaced our air handler in December 2014, We replace the filter every three months. The filter purchase from Amazon was the same "brand" as the original filter installed in December.

The filter works.  First time to replace it not difficult if you read the instructions. ( that is the difficult part, admitting that instructions may be helpful.).

My air purifier feels as good as new after replacing the filter with an official one.  Perhaps third party OEM filters work similarly well, but I'd rather not mess around with the air I breathe to save a few bucks.

As other reviewers have stated, these are NOT OEM or Hunter brand.  They are sheets of charcoal filter that you cut to fit your air purifier.  You can get two or three replacements from one order and they act and look just like the more expensive ones from Hunter.  Yes, they come in a Ziplock bag without any writing on it but makes it easy to store the left overs and/or put your used filter in before throwing it in the garbage. A great price and just as good as the name brand.

We purchased a Prolux  7000 about 2 years ago and needed to replace the hepa filter.  This was the best price available and was delivered on time! Would definitely use this vendor again.

The filter fits fine and seems to work just as well as the original filter that came with the purifier. We are completely satisfied.

My original filter was 23600.  The ones I received had a label of 23500 on them.  I thought they are the same as the web-site shows but unfortunately they are not.  the 23600 is about 1/4" higher.  I had to go to home-depot and bought some rubber floor mat to cut it out as a gasket and put on the filter to make it higher so the unit does not vibrate.

I purchased this filter from Amazon because they had the best pricing. I did my research on air filters and the green filter was recommended by almost every site as the top replacement. Delivery was quick and it installed easily. Very happy with my purchase.

This is less than half the price I paid from the local filter queen dealer in 2006.  I have been buying replacement filters on the internet for a few years and was very pleased that I could order them from Amazon along with the replacement filter for my Defender air cleaner.

I haven`t used this replacement filter jet but must praise the original filter in my AP-300 Air cleaner. Just love.. love... love... this machine. My air in my bedroom has never been cleaner and my allergies are much less. So pleased to have made the purchase of my two air cleaners plus filters. Katerelvis

fit perfectly into my "Claritin True HEPA 99.7 Allergen Air Purifier Tower Cap529b". Air seems to be filtered, but who knows with these things. I can't judge the quality of the product but it fit my purifier.

I received a Rabbit Air purifier from friend who was getting rid of it.  Purchased this and the carbon filter replacements - turned the unit into a brand new machine for me!
Works well as intended and promised.

Purchased with replacement filter:

I owe a 2007 model 5770 healthy home vacumn and am just now needing to replace the heps filter.  This filter is a perfect snug fit.  Highly recommend geting it.  It's even $15.00 cheaper than the filter on Bissell.com!
