Only thing wrong with these are the price.
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.

Fits my Honeywell perfectly
The pre filters fit my Honeywell perfectly. They arrived with no bad smell, have a nice thickness to trap dust, dog hair etc, and so easy to use and change. Amazon has the best price I have been able to find and will continue to purchase.

Does its job
Size is perfect for each of my air purifiers. Does help in trapping dust. Helps somewhat with strong cooking odors. I vacuum them to increase longevity with a small attachment.

Easier to use than cutting a large piece to fit
Iโve been using this type of filter and recently found this version thatโs precut to size. Not having to cut the filter myself made changing filters faster and cleaner.

Must Use These
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 Honeywell's. 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 we're talking REALLY small particle. The net effect was to make the room's air worse by blowing the particles around. These work perfectly. The HEPA filters fit very snug; in fact a bit difficult to insert. The unit is once again working great. So, yes, these cost more but they are worth it. Absolutely buy these IMHO.

Make sure you order the right size, and all will be fine
It's exactly what you would think - the official replacement outer filter for the specified Honeywell air purifying units. This isn't the internal HEPA filters, but considering it's a multi-layered approach, I think it's important to use these too - if nothing else it keeps a lot of the bigger stuff from clogging up the more expensive filters. The model numbers can be a little confusing, and this box was a lot smaller than I expected it to be, but it was just because the filters were folded up inside. A great value - essentially two years' worth of outer filters if you only have one purifier, or a year if you have two.

These work.
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.

Fit perfectly and good price
Happy to find 4 filters at a reasonable price. We really appreciate the air filter and find that there is so much less dust around especially for a severe asthmatic. The only drawback was the price of replacement filters so we were very pleased to find a box of 4 which is a year's supply of the A filters at a reasonable price. They fit perfectly and were easy to install.

Much better than old replacements
The updated material is substantially better than the old replacements with much better density and quality. It fits the HPA300 correctly.

Solved honeywell manual error
I was have a very hard time finding the proper pre-filter to fit my Honeywell Insight HPA5250. The included manual gave filter model numbers that simply do not fit this unit. As the manual was for full line, it looks like they only gave the smallest filter part number. I decided to shop by size instead and chose this 4-pack which is for the the largest unit in the Insight line. Using the old filter as template, i trimmed to fit and solved the problem. I ended up with enough left over to also replace filter in my old HPA-051c! I will be able to replace filter in my HHT-011c as well with left over trim from next Insight replacement.

Quality not bad
Had to cut to size but quality seems decent. I was worried it would be more see-through and thinner.
