Alen A350 Air Purifier
Alen Corporation is a relative newcomer to the air purifier business. In 2005, they pushed their way into an already
crowded field with a series of air purifiers designed to meet most consumers needs. The Alen A350 is one of the products
central to this line. With electronic controls, HEPA filtration, and a lifetime warranty, the A350 has made an immediate
impact on the air purifier market.
What I like about the Alen A350
The A350 comes equipped with push-button, digital controls. The
interface is user friendly and self explanatory.
Weighing just over 18 lbs., this unit is lightweight and compact. The ABS body blends easily
into any surrounding decor, and the A350 is one of very few units that can be mounted to the wall.
Though Alen does not use any sort of trademark to signal how quiet this unit is, the A350 is nearly
inaudible on the lowest setting. It is so quiet on the first setting that aside from the clean air coming
out of the exhaust vent, you wouldn't know it was running. On the second setting the noise level does pick up,
but not so much that it would disturb anything. On the two higher settings the noise levels are similar to comparable
models set on high.
Like all models that Alen produces, the A350 is easy to use and maintain. Use is
simple and straightforward while maintenance consists of removing the front cover, pulling the
filter out and putting a new one in its place. The entire process took me about 30 seconds. The
filters are not particularly expensive and come packaged with the HEPA filter and pre-filter together.
Additionally, should the pre-filter become clogged with debris before the time to replace it, it is fully washable or can be vacuumed off.
The A350 is energy efficient and easy on the wallet. It is Energy Star rated and uses about as much electricity as a
standard light bulb.
One key component to all Alen air purifiers is the warranty. The A350 comes with
Alen's standard Lifetime Warranty. With proper filter replacement (every six months), Alen
ensures that should their product malfunction or ever go on the fritz, you will be covered.
This kind of peace of mind is nearly unmatched in the industry.
What I do not like about the Alen A350
Though the Alen does come with a lifetime warranty, keeping your warranty valid is contingent
upon replacing the filter every six months. This is reasonable when compared to similar air purifiers.
Just remember to keep your receipts!
While its particle filtration may be excellent, the thin layer of activated carbon on the backside of the HEPA filter
is hardly enough to adequately handle odors, smoke or VOCs. Alen attempts to address this by offering a smoke/odor
filter which can be purchased separately.
On the top two speed settings the Alen A350 is not particularly quiet. While the lower
two settings place it ahead of its competitors, on the higher settings it falls back into the rest of the pack.
Overall, the Alen A350 is an excellent unit. For consumers seeking excellent particle filtration results
for medium to large rooms this model is an excellent fit. The price, ease of use, convenience, efficiency and
lifetime warranty all make this a very attractive product. However, those who need odor, smoke or VOC filtration
should consider another model.
