Excerpt: These are beautifully working products. They combine four kinds of purifying technologies (HEPA, Prefilter, UV, and Carbon) to get your air the cleanest it can possibly be.This model covers about 650 square feet so I purchased the two pack in order to have one upstairs and one downstairs.I really...
Summary: Ok had to return 1rst after short usage but company was very compliant to desire, a little loud, but is easy to move around and we seam to be enjoying "assumed" benefits of having one, this year 2014 being the worst for allergies is many years
Summary: Have a 3 year old with allergy induced asthma. Having this thing running is like having a window open all day without any of the dust and allergens getting in. The air feels refreshed and clean when you breath it in.
Summary: The Alen A350 Purifier arrived and was plugged in within minutes. We both noticed a reduction in eye irritation fairly soon after, at least by the next day. It's nosier than I expected though so we keep it on low.
Summary: Thank goodness this company has good customer service. I shipped mine down to the Caribbean and within a few months it stopped working! I wrote them and they didn't hesitate to send me a new one without me even returning the old one yet.
Summary: 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.
Summary: I've owned this filter for about six months. It works okay, but is not that great for allergen removal. Of course, I am using the basic filter which came with the unit. Upgrade filters could be better. It is easy to operate, but is somewhat loud at the higher settings.
Summary: The unit that arrived had stains and marks from previous ownership. Moreover, the filter with the unit was not new and had dust from previous use. Very disappointing. The first thing to do is return to Amazon/ Alen Corp.
Summary: I will be honest, I have only owned this product for a week however within the first few hours it made a significant difference in our living/dining area (we did have a Honeywell 50150 that has been moved to another room in the house).
Summary: For a Manhattan apartment with New York "crud" floating in.from outside. Not a complete answer. I judge the value of this item by how much less dust I find on furniture. Not working quite as well as I hoped.
