Let me start off by saying that I suffer from being allergic to cigarette smoke and my husband and I live in an enclosed apartment complex. This is made worse by the fact that the front door doesn’t seal up against the frame and smoke from the hallway leaks into our apartment with other odors and smells. Now let me add that that my husband suffers from severe allergy’s and takes medicine daily for his condition. Did I mention that we have two cats and a pug. Life was miserable in our 2 bedroom 2 bath apartment, till this little puppy showed up. It’s just like the picture describes it, like a barrel, the nice feature on it is the Intellicheck, this little feature tells you when to change the filters and it’s quite easy the pre filters just lay on the hepa filter and are held in place by two pieces of Velcro. They do need to be changed about ever two months though, this may be more then normal because of our pets. But since we got the first one for the living room we added one more to the bedroom. Now you walk down our hallway gagging on the scent and odors but as soon as you open our door you are greeted by the clean smelling air and the sound of the filter cleaning it. Okay it is a little loud but don’t let that discourage you. Wait till you get it home and turn it on full blast. It is a little noisy but when you go up to it, you can feel it sucking in the air from all around the unit. Then the freshly cleaned air gets pushed up through the top of the unit in a circle around the unit. It really does clean the square footage it claims to. Now I no longer complain about the smoke in our apartment and my husband also enjoys less sinus and nasal pressure. We did our homework on this one and read all about the Honeywell 50250. Before we decided to buy ours and were glad that we did.

Going strong after 3 years!

We have had this running day and night for 3 years and it is in great condition. There are no strange rattling noises or clogs like you see in some other air purifiers. It provides a nice ambient noise and it not too loud (on the lowest setting).

VERY well constructed and highly functional, but kinda noisy.

This thing is simply massive; it DWARFS one of those water cooler 5 gallon jugs. It’s simple, looks nice, and highly functional. The quantity of air it moves even on the lowest setting is nothing short of staggering, it seriously moves more air than my dual window fan and it ejects it in a perfectly even cone with no one area having a stronger flow or different direction than any other area.

Improved our symptoms from allergies!

Just received our air purifier in the mail yesterday. It took me a minute to understand which plastic to take off before wrapping pre filter on the purifier. There is this plastic mesh wrapped around the filter inside. You do NOT remove that. I called the number on the package and was told to leave the mesh in place. The black filter marked “A” wrapped in plastic is what it is referring to. Just unwrap the black filter and install over the mesh part and hold in place with the velcro. After doing this, I plugged it in and have had it going on high in our open floor plan living room. The sound is a loud fan type noise but I like that because it drowns outside noise. We have partially carpeted home with a dog and cat and do not smoke. So far, I have noticed that I can breathe better. Also, My husband has horrible allergies and currently off medicine for his upcoming allergy test. So far, he isn’t having the issues he had before when he was on medicine. I have the purifier placed by our HVAC air intake so it seems to be cleaning the air in the full house. So far this has improved our indoor air quality and improved our allergies. I am planning on buying a second one for our house.

This product it is not loud like everyone says. It’s highest setting is quieter than an airconditioner/fan. The lowest setting you can’t even hear. Slight chemical smell initially bc of new filter but dies off in first 10 minutes. Have had it running 20 hours and air qulaity of whole apartment improved greatly.

In this review, I will first summarize the major points and focus the details afterward. This way you can stop reading when you get the level of details you need. The definitions of “HEPA” and “CADR” are placed at the end of this review. Please vote for this review if you like it 🙂 I appreciate it.

I’m not sure if it’s working (UPDATED) It is Working!!!

I’m not sure about this unit yet. I’ve been running in continuously on mostly the very high setting for 5 days now. I would have expected to see some kind of evidence on the filter that it’s working. At least a little dust.

We’ve used all types of air purifiers and filters over the years, from the trendy ion types to regular HEPA filter units. These did a somewhat mediocre job at cleaning and filtering the air, but the Honeywell 20250 outperforms them all with visible results.
