Honeywell HRF-A300 Air Purifier Pre Kit Filter, 4-Pack - Allergen Air Filter Targets Dust, VOC, Pet, Kitchen, and Wildfire/Smoke OdorsCompact by Design (Amazon-developed Certification)

Great Product, fits perfectly and seems to do a great job with air filtration. Will definitely buy genuine replacement parts from Honeywell again.

The filters are affordable and came quickly. They were easier to find on Amazon than in the store!

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.

WOKS GREAT, I THINK ITS TOO EXPENSIVE TO HAVE TO REPLACE EVERY YEAR, $ 75.00 FOR 3 FILTERS IS A BIT MUCH.

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.

I always have these on hand to replace for our air filter. They work so well catching the dust and are sturdy and made well. The thickness is just enough that it holds everything it catches.

Love these replacements. Perfect package with everything I need.

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.
