AllerAir 4000 Air Purifiers
The AllerAir 4000 air purifiers are compact air purifiers that pack a lot of punch. Contained in its 17" tall housing
is 12 lbs of carbon (either VOCARB or MAC-B), specially blended to remove chemicals, odors, and gases. Powerful and
versatile, the AllerAir air purifier is loved by many for its economical value and industrial strength.
What I like about the AllerAir 4000
Very heavy duty. Like all AllerAir air purifiers, the AllerAir 4000 units are hard-working and heavy duty. They can
cover up to 1200 square feet, though we recommend you use it for 750 square feet or less, for a higher number of air
changes per hour. Not only can an AllerAir take on a large area, it is packed with carbon, providing the 4000 units
with serious filtration.
The air purifier housing is constructed from super durable metal that does not off-gas. The AllerAir both looks and feels
like it is built to last. The heavy-duty housing is coated with a baked on enamel finish to both protect your filters and
resist damages and dents. The filters themselves have a decent lifespan. The pre-filter will generally be the first item
that needs to be replaced, but vacuuming this item periodically will extend it beyond the approximate three month change
interval. The carbon will need to be replaced every 1-3 years, and the HEPA filter on these units generally lasts 3-5 years
depending on usage.
The UV light option is ideal for sterile facilities, hospitals, labs, daycares,
and clean production areas. You'll also be
interested in this option if you are allergic to mold or just get sick a lot. The UV lamp destroys antigens and pathogens by
emitting ultraviolet waves, which alter their DNA as they pass over the lamp, making them harmless.
Starting under $500, an AllerAir air purifier is a highly affordable way to remove high levels of air contaminants,
even in extremely heavy duty applications and industrial environments. With a high fan speed for wide area coverage and
several pounds of carbon to remove high levels of odors, chemicals, and gases, this air purifier is a great deal for
heavy duty applications and industrial situations.
What I do not like about the AllerAir 4000
I found the AllerAir to be hard to maneuver. Though the casters do make it easier, it would be helpful if there were
side grips or handles. The cylindrical shape can be a bit difficult to hold onto. At around 40 lbs, the 4000 units are
also quite heavy. Of course, it's heavy because it is constructed from durable materials and packed with odor and
chemical-removing carbon, which are necessary for heavy-duty jobs. Still, you probably do not want to move it up and down stairs.
The control panel is very simple. There are no markings on the dial to show which fan speed you are selecting you just
have to listen to the change in noise level. However, it is no more difficult that operating a ceiling fan and is not a
problem once you get the hang of it.
Admittedly, the AllerAir is not the most attractive air purifier available. It looks very industrial I did not
think it blended very well with the decor in my house. However, it's great for jobs where function is more important than form.
In summary, the AllerAir 4000 EXEC and VOCARB air purifiers are great at what they do. It is designed for economic, powerful,
and versatile control over significant amounts of contaminants and they do a terrific job. It is recommended for industrial
strength applications such as construction environments, restaurants and bars, artist's studios, basements and attics, and
maybe even a large family or all-purpose room inside the house.
