Honeywell HEPA Air Purifier Filter Replacement Kit for HPA300, HPA3300, HPA5300, HPA8350 series Air Purifiers, Value Combo Pack Includes 3 HEPA R & 4 A Carbon Pre-Cut Pre-Filters

Good fit and good Honeywell product

Great filters that work!!! they do exactly what they are supposed to do. Take all the particles out of the air so your body doesn't have to. I have recently tried some knockoffs that seem to be performing as well as these for a quarter of the the price. By having multiple units in my house it seems to greatly extend the life of the filters. I keep an eye on the pre filters and will use the shop vac to clean them off and usually replace every six months instead of three. The HEPA filters often last 18 months or more. Put them in your cart and keep an eye on the price or set an alert on camelcamelcamel.com when they drop in the $60 range stock up or give the knock offs a try.

Can be cleaned and reused, one piece of it. Expensive but worth it for clean air

I have been using these filters for years. I know they work to clean the air since my A/C filters do not need to be changed that often. The last time the A/C filters were looked at, they looked new. I have 2 of the Honeywell air filters working full time in my house. They are easy to replace and last me about 6 months.

I once tried cheaper replacement filters, and they didn't fit properly about half the time. These filters are expensive, and everyone knows that the materials and manufacturing process is like 1/3rd of the cost they charge. But, these are high quality, and they just work. You dont have to worry about corners being cut by shell companies that hope nobody notices that their filters don't work properly before they can disappear. Definitely try not to pay full price - when they are on sale, gobble up a little supply of them. At full price the cost is kind of brutal. Anyway, unlike a lot of cheaper HEPA filters that seem to go months without discoloring much, they work very well. I work from home, and keep a Honeywell console filter in my office and another in our bedroom. The productivity boost from cleaner air that does not trigger inflammatory responses is actually tangible. The carbon in the prefilters is high quality and dense, and the HEPA filters last, for me, about 6 months as long as I keep the carbon filters replaced correctly. Four stars for high quality .Minus one star because everyone knows that Honeywell is absolutely ripping people off with the cost vs the cost of materials and manufacturing.

Very good filters. I will order again

I live in a really dusty area. Due to this, I can't let my filters go past the manufacturers recommended swap out timeframes of three months for the pre-filters and a year for the HEPA. Before finding this kit, I was buying the pre-filters and HEPA's al a carte. The pre-filters I was buying were the Honeywell Type A+ pre-filter (HRF-APP1V1) and they were a pain to work with. They're a large cut of the Type A+ filter and you have to trim it down to fit your filtration unit. They're also thinner and more translucent than the one that comes with a new air purifier. Making them annoying to install. This kit comes with four pre-filters and all three rectangular HEPA filters for the HPA3300, which is a full year of service. The pre-filters are like the ones that come with the new purifiers. They're dense and precut, which makes them easy to install. My only issue is the price on these. They're name brand and do a great job, but they are just paper and cloth in the end.

Haven't found a better air purifier. Tried the Shark never replace and it failed within a year. Must have for my dog. Fresh filter vs 3 months is night and day.
