DerBlue 3PCS HAPF600 HEPA Filter Replacement and 3PCS pre filter Compatible with Holmes HAPF600 HAPF8650 HAP615 HAP625 HAP650,Replacement Holmes Air Filter,Part # HAPF600, HAPF600D, HAPF600D-U2

The items arrived as promised. The HEPA filters fit well in my Holmes purifier. Am a little disappointed in the pre-filter. The pre-filter was cut a little short in both length and with. It doesn't cover the entire HEPA filter like the previous pre-filters I purchased. Overall, it is a good product for the price.

Excellent DerBlue!First, shipping was excellent! The items were packed and sealed and perfectly fitted into the box, with absolutely no damage.Second, I cannot tell the difference between a Holmes filter and DerBlue. Everything is exactly the same with thickness, pleats, and fit.It was easy enough to change out the filter on my small black Holmes air purifier. The included carbon filter is nice and thick and fits perfectly into the holding tabs on this “B” style HEPA filter. The mounting tabs are OEM thickness and no worries about breaking them as some other reviewers have stated with brands other than DerBlue.I purchased the 3 pack (6 items total).In the future, I will only be purchasing DerBlue filters.

That's how I reacted after installing these HEPA filters (with carbon filters). The air cleaner with these new filters attached now makes a whooshing sound on the highest setting -- as though the air is not being drawn in unobstructed. I even turned off the machine and took out the filters to examine them, and they looked as they should. After reinstalling, the machine still made the sound. So I cannot tell how much of the air is actually being filtered through.

I didn't even realize I needed to replace these filters every year. I've just been hobbling along with my old ones for far too long. So when I realized I could replace them at a reasonable price, I bought these right away. They fit right in the slots, no issues or problem. So, there's not a lot to say about them....they aren't the "sexiest" product I ever bought but they do exactly what they are supposed to do without fuss or hassle. I have determined zero difference in the expected operation. They are quiet and seem to filter the air just like they should.

Fits perfectly in my Holmes air filter.(HAP8650B-U) It's perfect because it comes with three which is the exact amount I need for a fraction of the price of other retailers.

These are great quality filters and I feel possibly even better quality than the original ones that came with the air purifier. Definitely a great value and no reason not to get these! I am always concerned about quality and have no concern about these filters at all.

Perfect fit, perfect price and finally the perfect amount of filters to fit my air purifier (3). DerBlue is awesome! Not only do you get the hepa filters, you get the charcoal filters as well. Oh, by the way, delivery was perfect as well. Again, PERFECTION !

Works perfect. Much cheaper than the name brand ones and these are well-made and I could tell a difference in the room after I turned it on.

fits and works great
