Durabasics 3 Air Filter Set for HPA300 Honeywell Air Purifier Filters & Honeywell HPA300 - Compatible with Air Purifier Replacement HPA 300 - Replacements for Filter R & HPA 300 Filter

I’ve bought other filter replacements for my air purifier and they fit very loosely and would fall out when I opened it to change the filters and they just seemed cheap. This brand that I just bought fit so tightly they will not budge. They seem to be much better quality than the others I’ve bought. They felt heavier and thicker. Especially the prefilter felt much thicker than the other replacements I tried. These filters seem to be just as good quality as the original Honeywell filters that came with the purifier, I just did not want to pay the higher price for those when these seem just as good and for a good price.

Perfect fit and much cheaper than the original replacement filters.

Yes, exact fit and works just like the Honeywell product. I have ordered this before.

I've 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 neighbor's fireplace.) These Durabasics filters weren't a perfect fit, but pretty close. I could swear the air purifier's 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 they're 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, they're worth every penny. I like the fact they're relatively inexpensive as I would rather change them when they are visibly dirty instead of trying to vacuum them, which won't remove the smallest, most dangerous particles and even if it did, releasing them from the filter is the last thing you'd want to do.

Worth it!

Great fit for our Honeywell HEPA Air Purifier, specifically the 2400sqft model. Easy to replace and makes a difference in the air quality. This is probably the cheapest one on the market compared to other sellers. I've purchased this multiple times!

I have an older filter and this fits it great.

A good product

Fit is excellent for HPA300. Works well.

Four levels. The higher two are a little louder, but the higher levels purifies the air more efficiently. The noise levels are tolerable. Fairly priced. Installation is very easy.

Easy to install, good value for the cost.

When installing these filter's , I couldn't see any difference in fit, quality or performance . These are much more affordable than the origanal brand with out compromise . I'll be using these from now on and I highly recommend these filter's to other's .

much cheaper than the OEM filters AND I didnt realize it came with 4 carbon filters too. These are the stiff ones like those that came with the machine (the replacement OEM ones have been very thin). At a fraction of the price, I will now be replacing the filters much more often. They fit perfectly too
