Durabasics 3 HEPA Filter Set for HPA300 Honeywell Air Purifier Filters & Honeywell HPA300 - For Honeywell Air Purifier Filter Replacement HPA300 - Replacements for Honeywell Filter R & HPA300 Filter

Works just as good as a name brand Honeywell for way cheaper.

Perfect filters, durable and easy to install!

The hepa filters are easy to install. But the pre filter is a little small (1/2-1” short of the top.) I have the Honeywell 5300B I think. The larger black model. The air coming out smells fresh and the purifier will run with the shorter filter. But I doubt it’s working as well if there’s a gap.

Good quality filters and price was very reasonable. I would order from this company again.

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, the Durabasics HEPA 13 Filters for 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 Durabasics 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 Durabasics carbon pre-filter and looked at it against the light and realized I could see right through it. I installed a second Durabasics carbon pre-filter, 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 Durabasics. 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 Durabasics filter is not packed with as much carbon as the one made by Honeywell and it just is 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 filters that make the air purifier effective and I had sabotaged my air purifier with a cheap carbon filter.

Helps asthma patient

Ive got a couple HPA 300 units that I use for general dust reduction. (I have IQ Air and Austin Air units with large charcoal filters for fire season and neighbors fireplace.) These Durabasics filters werent a perfect fit, but pretty close. I could swear the air purifiers output diminished slightly but I have no way to measure, other than hold my hand above the unit and see where I feel the airflow. How well do the HEPA filters work? People say theyre terrific without any way of knowing. The particles of most concern are too small to see, so unless you have a serious test instrument like a Dylos, there is no way to tell. Like any filter, pulling a lot of air through will collect visible dust so for that, sure, theyre worth every penny. I like the fact theyre relatively inexpensive as I would rather change them when they are visibly dirty instead of trying to vacuum them, which wont remove the smallest, most dangerous particles and even if it did, releasing them from the filter is the last thing youd want to do.

You should see the dust that this system filters out of the air. We noticed that we were coughing and sneezing but didn’t know why. I would recommend this Honeywell air filter.

Purchased before and they work.

Just like or as good as OEM filters.
