Honeywell HEPA Air Purifier Filter Kit – Includes 3 HEPA R Replacement Filters and 4 A Carbon Pre-Cut Pre-Filters – Airborne Allergen Air Filter Targets Wildfire/Smoke, Pollen, Pet Dander, and Dust

I love my hepa filters. So easy to switch out and they do the job.

Filters fit perfectly. Were not thin or flimsy. Did not need to be cut to size. Absolutely no odor. Maybe improvements have been made since the other negative postings?

This worked great and shipped quick. I have two large home air purifiers and this makes it easy to keep the air clean

This filter kit is the perfect fit for my Honeywell 300 series air purifier. The only con is the price. For the benefit of those reviewers that claim they must cut the pre-filter, I would suggest that you pay attention to what you are ordering. Honeywell makes three sizes of purifiers, the 100 series, the 200 series and the 300 series. Please note that the 100 series uses 1 HEPA filter, the 200 series uses 2 HEPA filters and the 300 series uses 3 HEPA filter. The pre-filter is sized fit accordingly. The attached photo shows the models that the filter kit is designed for as noted at the lower right corner of the box.

After paying $225 for Honeywell HPA300 True HEPA Air Purifier, the Amazons Choice for HEPA air purifiers for large rooms, I wanted to order a one year supply of the carbon pre-filters and of the HEPA filters, but the Honeywell replacement filters set was not available. So I made the mistake of not waiting for them to comeback in stock and ordered an off-brand version of filters that fit the Honeywell HPA300 Air Purifier, which, I soon found out, are less expensive and COMPATIBLE, but definitely NOT COMPARABLE with the quality and fit of the filters that come installed in the Honeywell HPA300 Air Purifier. After 3 months, I replaced the original carbon pre-filter with one of the off-brand carbon pre-filters. I slowly started to realize that the air did not smell or feel as clean as before. I had to run the unit on higher settings longer and more often, and the air was never as clean as it was before. Even the sound of the unit had become more annoying. After 3 months, I expected the warning light to come on to tell me to change the filter, but I kept waiting and nothing happened. Thats when I took out the off-brand carbon pre-filter and looked at it against the light and realized I could see right through it. I installed a second one of the off-brand carbon pre-filters, because it was all I had, but I immediately ordered the Honeywell True HEPA Filter Value Combo Pack for HPA300 Series Air Purifier. When the Honeywell filter set arrived, I immediately replaced the carbon pre-filter in the unit. The filter was more solid, heavier, thicker and less see-through the the less expensive off-brand ones. On the lowest setting, immediately the air felt fresher and the smells vanished. The sound of the unit got softer. This is why I bought the Honeywell HPA300. I suffer from both allergies and chemical sensitivities, and the carbon, now I know, is what traps and removes the perfume and chemical fumes, as well as smoke and odors. The off-brand filter was not packed with as much carbon as the one made by Honeywell and it just was not up to the task. COMPATIBLE, but definitely NOT COMPARABLE with the quality of the filters made by Honeywell for the HPA300 Air Purifier. It is the filter that makes the air purifier effective and I had sabotaged my air purifier with a cheap carbon filter.

You will need to change black charcoal filter more often, but this set will have you prepared when you need to change the white hepa filters too.

After much research, I originally ordered the best generic version of these. Bad idea. The outer (black) macro filter was the right shape but less fine than Honeywells. But the generic version failed because the HEPA filter did not fit snuggly, letting all sorts of particles be drawn through the admittedly very small gaps, but then were talking REALLY small particle. The net effect was to make the rooms air worse by blowing the particles around. These work perfectly. The outer filter is finer and the HEPA filters fit very snug; in fact they are a bit difficult to insert because they are so snug. The unit is once again working great. So, yes, these cost more but they are worth it. Absolutely buy these IMHO.

My Honeywell purifier is about 5 years old, and this filter set works fine. You only have to trim the inner liner to the correct size - which in the end, gives you extra inner filters.

Easy to change. We did both and odor from old house is gone.

Trust in Honeywell. Only gripe is the pre-filter is not precut, but not a big deal to measure and cut. Not worth complaining about, only stating for sake of disclosure.
