Expert Reviews


What reviewers liked

Patented HEMI-spheric HEPA technology helps filters particles as tiny as 0.3 microns.
I feel extra satisfied using the new control panel, as it is really clear and helpful.
This air purifier has a unique design. It looks like a tall tower. Through the body is the ventilation system that sucks air and releases filtered, clean air.
This Therapure model comes with a patented HEPA type filter that is certified to eliminate cigarette smoke, pet hair, odors, spores, allergens and other pollutants with a high level of efficiency. Its CADR ratings for smoke, pollen, and dust and are also above 100.
There are no needs to replace the filter. But a clean filter indicator will remind you when you should clean the filter to keep optimum performance.
Relatively low annual costs, which includes routine filter replacement (if any) and annual operating costs.
The controls on this air purifier are easy to reach, and you may switch the unit off, change the timer, and set the fan speed in seconds. You need not have technical expertise to run this unit, and you may ask anyone else to set it if necessary.
Energy Star Certified
Cleaning the filter is really easy too – you need to remove it from the unit (it pulls out easily) and simply vacuum it with your standard vacuum cleaner. In terms of maintenance, it really does not require much!
It's easy to clean.
We like that it is easy to clean, quiet, lightweight, portable and eliminate all household odors. It is extremely powerful
One of the selling point that really stood out is its 24-hour timer, seeing that it’s the only model on this list that offers such a convenience. Along with convenient dedicated controls for the ionizer and UV bulb.
With 3 fan speeds, a filter clean reminder, automatic timer control (from 1 to 24 hours) and the ability to purify a room up to 200 sq. ft., this air purifier is hard to beat.
Envion air purifier features a permanent HEPA-Type filter that makes it easy to maintain. The patented hemi-spheric HEPA type filter eliminates dust, pollen, odors, pet hairs and any household toxin. The air purifier has 3-speed fan along with the 24 hour timer that is easily control via the digital display.
It’s easy to clean the filter. All you have to do is to remove the cover located at the back, and then pull out the filter to vacuum it. As advertised, the filter doesn’t need to be replaced, so to people wanting to save on replacements.
It is simple to set up. Just check if the polarized plug fits the socket and if the unit is fully assembled
Therapure air purifier makes use of powerful UV light that reduces airborne germs as well as bacteria. There is an easy to read digital display. Its filters are very inepensive and can be replaced easily.
It is fully-equipped with an impressive air purification system consisting of a permanent, washable HEPA filter, UV light treatment, ionizer, and photocatalytic filter. With this unit, you no longer need to worry about filter replacements.

What reviewers didn't like

Filters need changing every 12 months.
It is not a True HEPA filter, and the quality is much inferior.
Cleaning the HEPA filter may damage the filter, and you will never know if the air purifier is effective unless the indicator on display says so. If you are cleaning filters, every month then make sure you are gentle and not damage the surface of the filter.
Not very effective at removing dust, smoke, and pollen at its lowest speed, which could affect your comfort if you’ll run the unit in your bedroom at night.
Light does not go off, very hard to sleep through.
Needs regular filter replacements.
It is expensive, and you need to replace the air filters regularly.
Its CADR ratings are on the modest side of the spectrum, but it’s not the weakest of the bunch. It also technically doesn’t have any filters that need replacing since the HEPA-type filter is permanent and only requires regular vacuum cleaning, but the UV bulb (to which the photocatalyst filter is attached) needs to be replaced every year.
The filter and UV light needs to be replaced annually and is not a permanent filter
One key disadvantage for the TPP240 is that several users have reported durability issues and it doesn’t help that it’s only backed by a short 1-year warranty. Another more minor flaw is that it has a blue indicator light that’s so bright it makes it hard for people to go to bed at night!
