Replacement HEPA Filter & Carbon Pre Filter Kit For Honeywell 50250 50250-S OEM Part Number 24000 (1 HEPA + 1 Carbon Pre-Filter)

Having the filter run a few days now, and seeing how clean the air is currently (no dust visible when looking towards a sunny window.) The short of it is The Model 50255 will use this filter element: "BlueBird Filters Replacement HEPA Filter & Carbon Pre Filter Kit For Honeywell 50250 50250-S OE". And it being a reasonable price and being "Made in USA", I was more confident in it though initially this was a bit of a gamble as described folows: I bought this for a Honeywell (KAZ) air filter that I had rescued from someone's trash, The filter I had in it was one from another salvaged Honeywell filter that I had salvaged previously a few years earlier that had the fan motor burn out after running for 4 or 5 months (and that filter element had no numbers on it, but since it fit the filter I used it).. So this was a slight gamble for me as the model number of my filter was not listed though I suspected it might be a "Model series" as the actual model number for the unit I have a photo of, with another photo of the ID sticker that indicated it was a "KAZ model 50255". (so technically a "50250" series.). It was packaged very well. Even if the filter had not been bagged, I would have used it as the sealed box would have had very little air flow (so the filter would still be clean), but the bag builds confidence in the cleanliness for the consumer. The "Proof is in the pudding" as they say, and the last image shows the raised area the filter had to fit around to be considered "the right filter", and it is a very good fit, the product description as well as one of the reviews had mentioned the dimension, which is helpful more than people realize. (Height, Diameter of the outside and the Inside Diameter.) And most importantly- no odor. The rubber end seals of the Bluebird filter element are a soft elastomer that will conform and seal the top and bottom of the filter to the housing so only airflows through the filter media. I will buy this again in the future.

Quality product.

Filter arrived in just a few days, on the front end not the back of the delivery window shown on the product page. It is an exact fit. Only complaint and reason for 4 stars on easy to install, the filter had been squeezed knocked out of round probably during shipping. So, it took a little prodding to get all the parts back together. Filter was not damaged and appears to be working great. Have no basis to rate longevity, but would expect it to last a normal span of years. Would buy again.

I needed to replace the carbon filter wrap and I wanted to replace the True HEPA Filter as well because I noticed the filter was grey. It still had plenty of air moving through it but I run my Honeywell 24 hours a day every day. I would like to start by saying you can vacuum the HEPA filter but it doesn't help and could hurt the filter. The only filter you should vacuum is the carbon filter that wraps around the HEPA filter as that collects the large dust and hair debris floating around. The new filter arrived in good packaging and did have a slight plastic smell but nothing overly malodorous. I did take notice of the construction of the filter. It definitely looks like a HEPA filter however when comparing it to the original filter that came with my Honeywell it does not seem to have as many folds in the filter which I am thinking it means it has less surface area when compared to the OEM filter. By having less surface area I can only guess right now but it shouldn't last as long as the OEM filter and the airflow through the filter will be more restrictive. What does this mean? I would assume that this means the Honeywell will not filter the same amount of air as the OEM filter does and again it may need to be replaced sooner than the OEM filter. Another quirk is that this replacement filter is shorter than the OEM filter. I would think this could affect performance again if there is a gap between the fan and the filter then the air circulating isn't being pulled through the filter but is bypassing the filter. Again I would have to let this run for awhile to see results but I can tighten the base down all the way and I don't hear this replacement filter rattle in place so it seems like it is an "air tight" fit. Please see my pictures to get an idea of what I am describing. In the picture with both next to each other the OEM filter is on the right and this replacement filter is on the left. The 3rd picture is this replacement filter and the 4th picture is the OEM filter. I have been using this replacement filter for about a month or so now and I haven't noticed any difference with performance but I will check it regularly and clean the pre filter at regular intervals. I am satisfied so far with my new filter.

This HEPA filter lasts a REALLY long time. There is an enormous amount of surface area capacity for the dust caught to fill before the filter becomes stuffed. The actual machines these are made for last even longer, pretty much forever. I have been using one of those for about thirty years non-stop. It is amazing that the bearings don't wear away. Basically, these filters are so good because the allergy filtration systems they are made for are so good. Oh, and yes they work and catch dust particles. Don't count on them catching everything, though. They reduce free dust/dander, don't eliminate it.

good quality

Exactly what was needed

After reading some of the reviews, I wasn't sure what to expect - as in, if it would be any good. When I got it, it fit perfectly in my Honeywell 50250 and I've had no problem with it. The odd odor that was talked about, which was of just the scent of material used put it together, like a rubber or vinyl. After I turned on the air purifier, I could smell it a little but the scent was gone within about five minutes, if it took that long. As far as value for money, it could be a little bit cheaper but at the same time, my original Honeywell filter was in the unit almost 9 years and truthfully I probably could have kept it, since it seemed to be working fine. Still, after all of these years, a replacement seemed prudent.
