OVERVIEW: The Alen A375UV Air Purifier that I own is a nice upgrade from the earlier A350 which I reviewed on Youtube. The A375UV is essentially the A350 with additional Ultraviolet light added (Hence the "UV" in the name) and a Tio2 catalytic post filter which essentially improves the Ultraviolet light benefits.
The difference ultraviolet lights ability to kill germs, bacteria and viruses. This is a nice addition which many air purifiers do not address. While HEPA is essential for dust and pollen removal in cases where allergies are an issue - removing germs and bacteria are also a factor in a weakened immune system.
The nice sized HEPA, Carbon and prefilter shows this air purifier as having nice range of features. However it comes with a very hefty pricetag of $599. It's not one of the more popular models on the market, and the price is definitely going to keep it from becoming more popular. The A350 is Alen's primary money-maker.
The replacement HEPA filter will last 4-9 months in the average home - $59 each = $120 a year
The replacement Pre filter/Carbon will last 4-9 months in the average home - $89 each so about $100 a year
Uv Bulbs will last 1 year and are on sale @ 2 for $59 - $59 a year
CONCLUSION: Maintaining the Alen A375UV will set you back about $289 a year (although you can probably find them for a bit less on Amazon, Ebay, etc.).
"Alen warrants your Alen Air Purifier to be free from defects in material or workmanship for as long as you own your air purifier. Buyers must register and Participate in the Filter Replacement Program. Two replacement HEPA filters are shipped to you every year on your registration anniversary for as long as you own your machine."The HEPA filter is $59 every 6 months" Even if you left the machine off most of the time, or did not need filter replacements every 6 months you have to buy them (at least the HEPA) to maintain the warranty. So "Lifetime Warranty" sounds great, and it is - for the Alen Corp.

I also take issue with the use of 'Lifetime Warranty" which sounds great but comes with a clause of having to be on auto-ship for a minimum of $120 a year (even if you don't need them). Plus you'll have to replace the UV or it won't be effective (another $54/year). Most filters like this one cost the company about $5 to make.
