 "Expensive box, cheap contents." 2009-04-27
By S. Vaughan (San Francisco, CA)
We bought this filter for our new apartment after several weeks of feeling terrible (congestion, puffy watery eyes, feeling tired, coughing, etc.) because we knew there was some sort of non-hazardous mold and dust combo at the root of it. This puppy looked like it'd do the trick, and for 6 days, we felt awesome. It worked very well! But on day seven the rotator inside this thing literally fell off the axle and ceased to work any longer. We were unable to fix it ourselves, and we found that once we opened up the packaging, we owned it. No returns were permitted, but we were allowed to pay for S+H back to the manufacturer for them to fix it. [...] The problem I have with this item is that the price is six times our cheap filters', and Alen's ghetto manufacturer hotline and inability to provide us with a new, working filter, indicates it shouldn't be worth this much.

 "It works & the cost is right." 2007-11-18
By Guy with sneezey wife (Florida)
I have been looking at and searching for a decent air purifying unit for at least 3 years, I find the cost runs way to high and the looks of the unit definitely wasn't designed by anyone with designing taste! And even though the germicidal UV light should be completely hidden from view most of the air filtering UV units I have looked at had obvious glowing of the eye damaging UV lighting.

Now for my review of this item,



The looks-acceptable.

Noise level-acceptable on low speed during sleeping.

Controls and adjusting-My wife has no problems working it! (Now that says a lot!)

The Glowing of the UV lights-Almost literally impossible to see!

Does it work?-my wife thinks Claritin cured her of her allergies. It took about 6 to 8 weeks letting it run 24-7 but it will clean up the impurities in the house and before you know it your not sneezing! Well it worked for me wife.

Would I buy another unit-Yes if needed.

The cost- acceptable

My only problem with it is "How would I know if one of the UV germicidal lights go out?"

I'm the type of person that probably never give out 5 stars to nothing, but I will give out 9.5 out of a 10 point scale for this item.

 "Just a Fluke I'm Sure" 2007-09-21
By Griffin (Florida)
I researched this product online and decided to take a chance ($500?!)...figured I had 30 days to decide. I waited a bit impatiently for it to arrive but when it did I immediately ripped open the package, plugged it in and....NOTHING. The thing wouldn't even power on. I'm sure it's just a fluke but for the money I decided not try this company again.

 "It was a present for my mom" 2009-05-05
By C. Rosario
I can't give a complete product review because this was a present for my mother who is asthmatic. It got there in great time and so far it's only been a month but she loves it and has said that it's not loud or extremely big. So for the price and the other good reviews I feel that this was a good buy!

 "Very quiet" 2008-09-29
By J. Rogers (Ohio)
It is expensive, but this is a very well made smooth unit that is very quiet. On medium it's still more quiet then the cheap fan in my computer. It does move a little bit of air, which can be cold if your sitting in front of it. So I moved it sideways, and now it does not blow air on me. The filter looks to be good with more cubic inches of actual filtration compared to the cheaper quacker box filtration units.

 "Exactly as described" 2008-04-26
By Brian G. Collins (Louisville, KY USA)
I ordered this unit last week and received it yesterday.

I must say, I am impressed and I knew I would be. This is such a great purchase. It has three speeds, the lowest is very quiet. I usually have it on 2nd speed because it is no louder than a small desk fan. The highest speed is about a loud as the AC on high, although I slept with it on high last night and didn't notice and I think I'm a light sleeper.



Overall, this product is great. The "ion" mode says it uses ions to make the room smell clean, but that is hard to tell. I will say, this unit makes my room smell a lot fresher and the air is better. The peace of mind with this unit is great.



The manual says it removes the common "pollutants" of Bacteria, Mold Spores, Pollen, Dust Mites and Viruses. Pollen and mold spores are 10-20 microns and a human hair has a diameter of 100 microns for comparison. So this unit traps very small, invisible particles that you would otherwise be breathing.



Must buy!

 "Excellent air filter for the price" 2008-04-02
By Nick Carrigan (Redmond, WA)
I received my first unit from Alen and it was slightly defective. The power switch worked, but the speed and Ion setting were flakey. After running the unit (stuck on low and no ion) the unit suddenly started working. I emailed Alen Product Support and they shipped me out another unit within 24 hours. I emailed them back to say it was working fine, but they insisted I get the 2nd unit anyway.



The 2nd unit worked as described and didn't have any problems out of the box. I am giving this product 5-stars based on its overall performance and the excellent Alen customer service.



I would also point out that this is not a "small" unit. At first, I thought it was meant for a desk or small stand, but this is 18" and a sleek 4-5" in width. The unit weighs next to nothing (and there's a smart cubby-handle) if you need to move it around often.



Removing the filters is a cinch and anyone can do this. However, Alen does recommend using gloves when changing out the filter every 6 months (if the unit is used continuously.)



The fan speed/noise factor is very good. The low setting is just quiet enough that one can easily sleep thru it (if placed in a bedroom.) The medium to high settings are probably going to be a bit too noisy if sleeping. It really depends on placement. At 10ft or so, you'll barely hear it running (on the low setting.)



The controls are well-designed and are easily managed. (The lights from the controls may light up a dark room, so that might be another reason to leave it off at night.)



One last note: the base of the unit does have a swivel. So the base stays one direction, and you can rotate the unit about 25 deg in each direction.

 "happy with my decision" 2007-10-30
By Erik Crimmin (Boston, MA United States)
i put this in my bedroom for the following reasons:

-i would wake up during the night and in the morning feeling slightly sick and groggy

-my room (in an old brick building) smelled weird



the day i plugged this unit in i noticed a difference in my bedroom. i don't wake up with a stuffy head and the air quality is noticeably better. in the end, i feel better about spending time in my bedroom and worry less about the air quality there.



i don't know what the ionizing function does and have not turned it on. only used the air intake filter.



i'm considering getting the t300 for my parents' living room. they have a wood stove that they love but burning wood leaves a grimy film on the windows and walls, not to mention what it must be doing for my parents' lungs.



i would highly recommend this unit for a small room.

Talk about the Goliath of air purifiers, the A350 has the power to clean air in rooms up to 800 square feet! As the leader of strength, it deserves a more regal place to sit than by a couch or chair so Alen made the A350 wall-mountable. Not only does it save space, but it can quietly disperse clean air over its domain.

The A350 comes with an ionizer that charges dust and pollen particles which has been shown in university testing to produce a benefit for many who suffer from respiratory allergies. Unlike other ionizers, though, the A350 does not produce ozone, making it the ideal alternative to common air cleaners.

With this much power and versatility, why Wouldn't you want one?

 "Fantastic!" 2009-06-01
By Christine Lloyd (Seattle, WA USA)
I received this unit as a Christmas gift (I've been suffering from some pretty nasty allergies), and I love it! It's fairly loud and high-throughput at the two higher speed settings, but it's whisper-quiet at the lowest setting and creates a pleasant gentle breeze. I've got it positioned under my (quite large) desk, so I usually run it at the lowest speed when I'm working at my desk and at the second-highest speed the rest of the time. It's a great white noise machine at the higher setting (we've got several neighbors with dogs), and it really has improved my allergies.

If I leave it off for a day or two, I start to feel the difference in the morning with stuffy nose and scratchy throat. It's been incredibly helpful. Also, the fact that it has a little series of lights to remind you when to change the filters is great. I haven't had to replace them yet (yay!), though it looks like I'll have to put in a new filter in 2-3 months. This is probably one of the best gifts I've received.

 "An Air Purifier to Avoid!!" 2009-05-25
By Donald L. Buckle (SW Texas)


My first Alen A350 failed within 30 days -- apparent blower wheel to blower motor mount failure.



After 1-1/2 weeks of emails, Alen did replace the defective unit.



Within the next 30 days, the replacement Alen A350 failed -- definite blower wheel to blower motor mount failure.



I'm currently writing emails again to get a third A350.



It is my opinion that either:

1.) the Alen A350 has a deficient blower mounting design; or

2.) the workmanship of this "Made-in-China" air purifier is poor.

Opened my product, set it up and turned it on and within an hour the fan began to squeek incessantly. It sounds like there is a deranged cricket in my house.

Our designers crammed a HEPA filter, ultraviolet lights (to kill those nasty airborne bacteria), and an activated carbon filter into the picture perfect tower of power! The HEPA filter weeds out those pesky allergens like pollen and dander while the UV rays kill off any rogue bacteria and viruses that managed to sneak inside your home. Combine these two powerful purifiers with an odor-killing activated carbon filter and you've got the T300!

You may have seen advertisements for tower air cleaners that use ionizers to charge particles and collect them on metal plates. The T300 takes that same sleek design but, instead of using powerful ionizers that could potentially expose you and your family to harmful ozone, Alen uses EPA recommended filters and purifiers. That's right! You get the style with even BETTER function! Not to mention HEPA filters are far safer to replace and clean than your usual metal plates.

 "Purifier works fine but UV lamps can be costly" 2009-05-27
By G. Kaligian
I purchased the Alen T300 this February and I've been pretty happy with the results. However, my major complaint comes from the fact that the UV lamp has already burned out and it just seems a bit ludicrous to have to replace a $79 lamp in four months. Of course, it's not covered under the warranty so along with replacing the filters for $45 every 6 months, now I have to replace the UV lamp even sooner. I don't know about you but it seems a bit steep!

 "Does the job" 2009-03-14
By Rick Buchanan (Roanoke, Virginia United States)
We've had this in our bedroom for about a year, with no problems. We run it 24 hours a day on the lowest setting, and the noise is not noticeable across the room when we're sleeping. Anything higher than LOW, however, is quite noisy, despite the claims. Operation is fairly easy, and maintenance is simple. Taking off the back cover reveals the two HEPA filters, which fit into two close fitting spaces. These are easily removed. The HEPA filters have a foam back pre-filter attached by Velcro-type tape. We vacuum these covers or wash them if they are particularly dirty, about twice a month. I have not had any problem replacing the back cover. If you line up the proper tab with the appropriate hole, and snap the top in, there is a beep which indicates the back is properly closed. There is an LED readout on the unit which purports to let you know when you need to replace the HEPA filters. The colors of the lights change from green to yellow to red. Supposedly when all the LED indicators turn red you need to replace the filters. I have no idea whether this is true. After twelve months the air is still noticeably cleaner in our room, and my wife's allergies are much better. I would buy this again.

 "Air purifier that really works" 2008-04-20
By Michael Costa (Marietta, GA USA)
Living in Georgia with all the pollen I developed allergies. I would sit in my den watching TV and find myself getting stuffed up and congested. That all stopped (with no medications) when I got the T300. I have bought several air purifiers but only the Alen T300 has made a noticeable and lasting difference in the air quality in my home. I own 2 and sleep with one in my bedroom. I sleep much better and can actually breath freely all night. I have had no problems with either unit and highly recommend the Alen products to anyone looking for a top rated trouble free unit.

 "A good quiet filter" 2008-03-12
By Michael Santaly (USA, NY)
I have been using the T300 for a few weeks now. It is a very nice Air Purifier. Its is a little loud on its highest setting but still not as loud as other Purifiers I have used. It has a lot of nice features like UAV light which can be turned off and on. It also has an ionizer which helps a lot if you have animals. The air smells fresher after only a few hours.



However I brought this unit mainly for dust removal. My room has a lot of dust, more than the average room and this unit while does filter a lot of the air, still can not make a dent in the amount of dust in my room. My room is about 170 square feet and used to be an attic. I don't think I can really blame the filter. I have watched it when the light hits my room just right, and I can see it takes in tons of dust. After a week I could not longer see any black parts on the pre-filter it was completely covered with layers of dust. While this filter might not be the best one for my room I will continue to use it seeing as I can't afford the more expensive units.
