When I first purchased the Honeywell Compact Purifier Permanent HHT 011 I was ecstatic at the thought that allergens,
dust and other air contaminants would be filtered, especially for the
price. My room is extremely dusty so I needed some sort of solution and
I hoped that this was it.
For the first six months the purifier
worked efficiently, or seemingly so. I ran the it, as recommended, 24
hours a day nonstop. When I'm not home I ran it on the high setting
(there are three settings), medium when I was around and low when I
slept. I cleaned both the outer filter and inner HEPA Air Purifiers regularly
as a lot of contaminants were being filtered. I noticed a somewhat
significant difference in the air quality of my room (11.5 x 8 ft)
during this span.
After sixth months the purifier was rendered
useless and actually made the air quality worse. The contaminant intake
became less and less, the dust in my room begun accumulating faster (I
still dust frequently) and the purifier's fan was blowing out unclean
air - air that reeked heavily of dust.
I highly doubt that the
HEPA filter is efficient forever and needs no replacement. It is
charcoal grey and transmits little light when held to a light source
(not sure if this is significant as compared to a car air filter test).
I do as the manual suggests and vacuum it (more frequently than
recommended) and I vacuum/wash the outer filter regularly. Another
review mentioned that the purifier became filled with dust and grime
over time; the same thing happened to mine, as evidenced when looking
down the air vent. I tried to clean it out by blasting 180+ PSI of air
with my air compressor, but it did nothing to help. The dust was very
thick, almost lint like, and would not budge at all.
To make
matters worse the purifier is fastened together by hexagonal security
screws (I'm sure the average household does not have the required
screwdriver). I recently bought the screwdriver and opened the purifier
to clean it out, and found that the inside was a horrendous mess.
Every surface and mechanism was layered with dust. The insides of the
tubular fans were coated with dust as well. The task of carefully
removing components to access all compartments for dusting was tedious
and took some time. I've cleaned almost all of the contaminants from
inside the purifier, but I am still very skeptical about using it again
in fear that I will have the same problem again, perhaps in less time
than before.
To sum it all up, this product was good for about
six months until the inside of the purifier became festered with dust,
and it was extremely tedious to remove it all. I'm not sure when this
accumulation of dust began, or for how long the HEPA filter has been
ineffective. The purifier does not filter all contaminants, instead
sucking some into the interior and spitting it back into the air in my
room.
With all of that being said, there are numerous positive
reviews on this product; perhaps I am an unfortunate rare case. For the
price I'd say it is definitely worth a try, but be cautiously
optimistic if you decide to make the purchase.
