Incredible results - a life changer!!
on March 19, 2014
Posted by: Janet
My husband had battled with allergies for over 25 years and had taken a variety of over the counter medications. His body had become immune to everything and nothing was working anymore. His sniffing, sneezing and annoying allergy habits were not only getting on everyone's nerves but he wasn't sleeping or enjoying the quality of life he so deserved. For his 55th birthday I desperately searched the internet for an answer to help him and discovered the Alen air purifier machine. The website gave wonderful suggestions and recommended the perfect size for a bedroom, since that is where most people spend most of their at-home time. I signed up for the filters to be sent to my door twice a year, at no shipping charge! The results have been nothing short of a miracle! My husband has not taken one single pill in two years. He celebrates his 57th birthday next month, totally allergy-symptom free! I recommend your product all the time and even loaned my husband's machine to a friend this week while we were on vacation. I am going to pick it up later this evening and hope it has helped her just as much!! Forever grateful :)

Alen 350 air purifier

Have used the A350 air purifier for almost 10 years. We have 5 units in our home. Also purchased a small tower purifier for the RV. Filters last 6 - 9 months before replacing.

use more than 1 season

We use our alen filters in summer and winter when the house is closed up from the cold or if the air conditioners are on..We have sinus problems and find the filters help a great deal...Also it really helps kill odors from the bedrooms and the kitchen. Our house is small so the one machine works fine for us.

Alen HEPA-Fresh Filter for the A350 and A375
on May 1, 2014
Posted by: Happy C.
We have been using Allen Air Purifier since 2005 and been very pleased with its quality and performance. The product design is solid and consistent to the newer model, thus, allowing customer with older machine able to use the same filter replacement (No worries of outdated/discontinued filter replacement).

So so

After reading the glowing reviews of the air filter, I was expecting quite a bit more out of it.
I am a light smoker and I use the air filter in a room with 240SF and a 10' ceiling.
For almost a week I ran it on high with both the UV & ionizer engaged. I could not tell any difference.
After that, I put it on low and let it keep running.. The room seems somewhat better but still not as good as I thought it should be.
As for the instructions: The last time I purchased something with instructions this poorly written was in the early days of Japanese imports.
I still don't know when or if I am to use the UV & ionizer functions, so I just leave them on all the time.
Also, seems a little odd that the power light indicates red in stead of green when the unit is on.
I would not buy this unit again.

Affordable and great features

I purchased a a350 and I was impresed with the air quaility since i was using this product . I was getting headaches and Since using this product with the silver replacement filter I have not had a headache. I have four dogs and the air is cleaner and no doggie smell. The unit is quiet and easy to use and has numerous features. The only downside is the filters are expensive. But overall I would recommend this product.

Superior product!

I am a huge fan of Alen products. The replacement air filters are fabulous and I love the automatic shipment. This filter arrived just in time as my son's allergies were starting to act up. I just swapped out the filter in the unit and ran it on high for a few hours and his symptoms subsided. These are also great filters for those with pet parrots. They keep the air clean and dust free for both humans and birds!
