Product Description

Product Description

The 50250S True HEPA Allergen Remover air purifier removes at least 99.97 percent of common household particles as small as 0.3 microns from the air passing through it such as dust, pollen, mold spores, tobacco smoke, and pet dander. The carbon activated pre filter helps remove common household odors while helping to extend the life of the HEPA filter. The patented 360 degree air intake and discharge maximizes efficiency, circulating the air and allowing for placement in any area of your room. This air purifier also features the Intelli Check filter monitor to remind you when to replace the filter. Statistics are from the air that passes through the filter. Overall particle reduction is dependent on many factors, including the amount of air processed, the pollutant type, and the pollutants introduction rate into the environment.

Customer Reviews

Certainly helps with the seasonal allergies and helps eliminate dust floating around in the air.
The high setting is borderline too loud but if it is not in the room you are sleeping in it just kind of sounds like white noise.
A. Moore
This is a well built air filter that seems to do a very good job circulating and cleaning the air.

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.

**Kimmer (another reviewer) has kindly uploaded a wonderful youtube video to demonstrate the noise level, title: "Honeywell Enviracare 50250 air purifier". Since your computer speaker will affect the demonstrated noise level, make sure you gauge the noise to Kimmer's voice.**

Pros: Powerful, inexpensive, permanent HEPA filter, easy to maintain, 360 degree air intake and output, portable, accessible replacement parts, good support from Kaz, a 5 year limited warranty.
Cons: Noisy, high power consumption, not stylish.

Previously I owned the Honeywell HFD-130 Germicidal Tower HEPA Air Purifier with Permanent IFD Filter, but due to its ozone emission and my respiratory problem, I returned it back to HomeDepot. I got fully refunded and bought this Honeywell 50250N on the same day and loved it. I have a mild allergy. I sneeze and experience itchy eyes when I am outdoor, but stop when I am at home (where my purifier is). I recommend two important points when shopping for a purifier: (1) always examines the CADR number. It is a decent performance indicator, (2) always buys an air purifier adequate for your need. A 100 sq ft purifier will not work for a 1000 sq ft living space.

Honeywell 50250N is a true HEPA filter purifier with a 250 CADR, which translates into a recommended 375 square feet usage space.

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.

I was about to actually purchase this, then, after reading everyone's reviews (good and bad) and researching on the Honeywell site and writing emails to Amazon support, Honeywell, and Kaz for product clarification, experienced the following:

- Amazon support wrote me to tell me they were researching and would get back to me in a week. Then a week later they wrote back to apologize, they were researching still, and it was taking longer than normal. Then I didn't hear back from them. In the meantime, I wrote them to tell them what I'd learned. I have yet to hear back.

- Honeywell's website DOES NOT LIST THIS MODEL - 50250-S doesn't exist on their site. They list 50250-N and 50250. As mentioned by another reviewer - 50250 has a different filter from the 50250-N he bought. The 50250-N he bought and described in happy supportive detail, however, is not the 50250-S you are looking at when you look at this product on Amazon for which I am writing this review. I wrote Honeywell asking about 50250-S and they told me immediately to contact Kaz Support, so I did.

- Kaz support wrote me back fairly quickly, and told me this:

"We did make different versions of the 50250 series air cleaners. The original 50250 came with a HEPA filter that could not be cleaned of vacuumed, and this filter needs to be replaced every 1-3 years, depending on air quality and use. The HEPA filter that comes with the 50250-S is easy to maintain and can be vacuumed to extend its life. It is not considered a permanent filter, and should be replaced within approximately 3 years depending on air quality and usage. The 50250-N is the only version of this series that came with a lifetime, vacuumable HEPA filter."

There you have it.
