Best affordable air purifier
357166
I've had this air purifier for about a year now and really love it. It does the job in our large master bedroom, which is as big as a NYC studio apt. We keep near our bed and put on the allergy setting at night. It's amazing how clear my sinuses are in the morning and how refreshed we feel. I live in an urban area, so it's also a good knowing the air in my home is clean. I bought the smaller version for my parents this Christmas. They put in their bedroom and noticed a difference the first night. They also suffer from allergies and sinus issues. Honeywell recommends the HEPA filter be changed once a year and the pre-filter every 3 months. I have found 2 months is best for the pre-filter since I have a medium size dog.

Effective Air purifier.  If you have any air quality issues, this and similar devices definitely help improve your indoor air quality.  Very happy with my purchase, wish the replacement filers were a little bit more affordable.

I have tried other air purifiers and these are by far the best!  I used a previous model that looks identical, for 12 years (running every day for 17-18 hours on the highest setting) and it still worked but the motor became noisy after so many years and decided to replace it.  I use it in my study which is 400 sf and it keeps the air clean from dust and cigarette smoke.  It's very quiet.  I change the HEPA filter once a year or so and the carbon filter every 3 months. Highly recommended!  One of the best products I ever bought.

We have been looking into new air cleaners because the one we had the filters were going to cost $30. We have had Honeywell in the past and had no issues for many years. With smoking in the man cave that the air can get prett nasty. We usually have it set at a one or two and have yet to be were it is not cleaning the air. The sound is not too bad compaired to some we have had. It is no louder then our fan. The size is nice because we can place it anywhere and it will fit. The blowers are very strong and moves a lot of air. I am very pleased with the purchase and happy with the results. The allergy issue has also cut down greatly with pet dander there is a lot of stuffed family members. This has greatly reduced the issues and plan to be putting more around my house. The cost to maintain this product is very low and worth it well over the long run. I bought this on the Amazon wearhouse deals and know they have them all the time for people to pick this up at a great price.

This is a very good purifier.  My wife is allergic to a list of stuff and the Alen is doing  a great job making her life less miserable. It is also a size she can move easily.  I will most likely get a second one.

I look for two qualities in an air cleaner, effective air filtration and silent operation. Blueair gets 5 stars in both areas. The lowest setting is suitable for night time operation in your bedroom. The middle settings can be used for daytime operation without causing a distraction. The highest setting should only be used when maximum cleaning is needed for short periods of time, it does produce a fair amount a noise. Filtration is second to none! Have one unit in my bedroom and one in the living room, every time I walk to the room I could immediately feel and smell the cleanness. Times when I have been out doors and suffering an allergy attack, I would go inside and sit in front of one the Blueairs and within few minutes be breathing easy again. Even though these units are not cheep, the improvement in my quality of life makes Blueair worth every penny. After a year of continuous these units have proven reliable and energy efficient.

Got this for a good price (discount coupon). Also own an IQAir which costs more than three times, so shouldn't really compare them.

Pros:

- A lot of Features for a really good price (UV light, Active carbon odor-eliminating prefilter for under $170.). Big bangs for the bucks!

- True HEPA filter!

- You can place it on the side of the room against a wall and still have the unit work effectively.

- Really like the active air quality monitoring sensor (which shows you the current air quality in realtime).

- Clean a lot more air than the expensive Ionic Breeze for a fraction of the price - please do yourself a favor and do a research on the net.

Cons:

- Somewhat NOISY for its rated cleaning air flow.

- Huge in size for its rated cleaning capability (don't be fooled by the tiny picture).

- Although my wife did not complain about the noise at night, she hated the constant cold breeze reaching her face while sleeping, no matter which location or how we positioned the air cleaner. So, I swapped it with the "breeze-less" IQAir for the bed room.

  The smaller clean air outlet(actually nozzle) of this Hamilton Beach air purifier causes higher airspeed and noice level even at the lowest speed setting.

We have had no problems so far with this air cleaner. I love that out had a timer and will automatically shut off. I mostly use the allergen setting and feel it works great. We use it mainly on our second floor which is one large and two small bedrooms with one bath. There are 3 filters in this model so be prepared to shell out some money when you have to change filters. Also its easy enough to move to other locations when the need arises. Sometimes cigarette smoke smell comes through from the house on the other side of us. This units makes quick work of cleaning the air and getting rid of the smell. We did try the next size smaller of this same model and decided you get more bang for your buck with the bigger one. Totally happy with it so far.

Have used several less expensive HEPA filters in the past with less than stellar results - the Blueair 501 cleans the air more thoroughly - I would wake up occasionally coughing before (most likely due to pet dander) - have not had this happen since running the purifier at night on setting "4" of 5.  I also have a neighbor who's second-hand smoke sometimes drifts in through the pipe fittings - the smell has disappeared, too.  This unit is more expensive but it's worth it - am very satisfied!

I am impressed with this purifier. I'm using it in a 2BR apartment alternating between a bedroom and the living area. Runs quiet, air feels fresh, sinus are happy. A E S T H E T I C A L L Y pleasing as well- why are most air purifiers so ugly? For the price I am very pleased.

HEPA filters on consumer air purifiers pretty much all do the same level of filtering, and so the only real variables are how much noise a unit makes, how much air it moves, and the cost to maintain. The noise on this unit is reasonable, especially for the volume of air it moves and the relative small footprint. I can understand why people complain, as it does sound like a large window A/C unit when on high, but there's really no way to make something move a lot of air through a small space and keep it quiet. It's just aerodynamics. You get turbulence when you blow air through a small opening. If you want a quiet unit that can handle as large a room as this (my recollection is this can handle roughly 400 sq. ft.) you're going to have to get a much larger purifier.

The second variable, room size, is really a product choice. I assume if you're looking at this one it will do the trick for you.

The last variable, cost of maintenance, varies GREATLY among all brands. Some purifiers require you to buy a new HEPA filter one a year or so, and that filter usually costs about as much as the original unit. On the other hand, this HEPA filter in this purifier is designed to be vacuumed out twice a year and will last the lifetime of the device. Even better, the prefilters (which are usually what get you with these things) are surprisingly cheap. Since the 17005 is relatively small, you can get two replacement filters out of the Honeywell universal prefilter packs, which are only $10. Given that you only need to replace these about once every 3-6 months, you can operate this purifier for $10-$20 a year. This is by far the cheapest HEPA-based purifier I've ever seen. You might argue the electrostatic devices are cheaper, but they have the significant downside of requiring manual cleaning, they produce ozone, and--most importantly--they don't filter nearly as effectively.

The only downside to the 17000 series I've found is that they have a tendency to vibrate. I had to go through a couple returns before I got one where the fan was properly balanced. This seems about par for the course; everything is cheaply made these days and it shows. Of course, this is quite a value for the money if you get one that works well. This issue is why I can't give it five stars, however.

All in all, this is the first air purifier I've been happy with. It's small, does its job well, and does so with minimal operating costs.

Well, I purchased this New Comfort 3500 HEPA Ozone Ionic Air Purifier in November 2015 and thought I would come back and write a review for anyone looking to purchase it. My husband has dust, grass and animal allergies. I did a LOT of research on purifiers for a 1360sq ft house. This has been running 24/7 on (Medium fan) air purifier mode since November 2015. I do not use the ozone feature as its very unsafe and toxic when the house is occupied (as stated in the manual only use ozone when the house is UNOCCUPIED) So far the filter has worked great! I vacuum it off and haven't needed a replacement. I did notice today while cleaning the filter the UV bulb was burned out so I purchased another UV bulb $25. Not too shabby.  As far as my husbands allergies go its helped a LOT! We lost one dog (who got hit by a car) and then the other went through depression so she was in the house more that before. This air purifier has helped and my husbands allergies have not flared or bothered him since we've had it. I wanted to add as a last note the cover on the back comes off easily and the filter comes out easily. I have weak arthritic hands and its no problem for me.

This purifier is amazing. We bought it to deodorize an RV that smelled like cigarette smoke. After wiping down the walls and ceiling, plus shampooing the carpets and upholstery, the aroma of smoke still lingered. Knowing that we would be unable to tolerate the odor, we investigated other solutions. An ozone generator seemed to be the answer. We researched generators on Amazon and believed the Fresh Air to be the best one for the money. Upon arrival. we placed the generator in the RV, turned it on for the maximum time, and let it do its magic. We were pleasantly surprised to find no trace of cigarette smoke remained, even after taking the unit on vacation.

We've used this ozone generator in a musty bathroom, also. No more odor. As for complaints about the chemical smell left behind by the generator, it is more like rainfall in an urban environment... fresh, but with an acrid tang. It doesn't bother me, as it's so much better than the alternative (smoke or mildew). Wait a couple hours before entering. Open a few windows and let some fresh air in. That's what we do. This is not a purifier that you run all the time, but it is amazing for problem odors.

Price appeared almost too good to be true. However; when it arrived I opened the box right away read the manual and plugged in.  Wow, it is really quite a must, in our home. Three out of four house members are cigarette smokers the need to Physically clear the air was a daily challenge.  Happy to report those days are gone. This mighty air purifier for under $100.00 no less when rotating can suck up the smoke within an hour and you'd swear there are no smokers. I bought extra filters, notice they sell 4 for $8.99 but they also sell 8 for $9.99 double amount for $1.00 more. I highly recommend this to anyone who needs to really " Clear the Air".

I purchased this air purifier after comparing reviews on several different brands.  It was significantly less expensive than some models that covered less square footage.  I bought it to help with my allergies. We have three cats of which I am very allergic too.  I put it in the bedroom and the first night I ran it was the first time in months that I woke up with clear sinuses the next morning.  It's quiet and I can actually smell the difference in the air quality.  Love it!

I needed an new unit because the one I had was not helping me. This air purifier does exactly what it is advertised it would do and it is easy to use.
