While the future of Envion’s products seem a little unclear at this point, it’s the perfect time to appreciate all the best Envion Therapure air purifiers while they’re still available here!

Envion Therapure Air Purifier Reviews

1. Envion Therapure TPP240-M

The TPP240-M from Envion’s Therapure series is a HEPA air purifier rated to cover up to 343 sq. ft. It starts off with a permanent HEPA filter, UV light treatment, ionizer, and a photocatalytic filter. What makes this unit so great is that it eliminates the need for filter replacements by only using permanent filters.

Unfortunately, users have reported that the TPP240-M isn’t as durable as it seems, and it doesn’t help that it only comes with a measly 1-year warranty. In addition, its blue indicator lights are so bright they can practically light up the room! It also does not sport a True HEPA filter, using instead a less efficient HEPA-type air purifier.

Overall, however, the TPP240-M remains to be one of Envion’s most robust and powerful air purifiers. At such a modest price point, the TPP240-M can be relied on to purify the air in small to medium-sized rooms and effectively remove a wide array of air pollutants from your home. On top of that, you get a fully decked out air purifier with a lot of useful controls.

Pros

  • No filters to replace
  • Best for medium-sized rooms
  • Decent CADR ratings
  • Affordable upfront and long-term
  • Can tackle a wide array of air pollutants such as allergens and germs
  • Optional UV light and ionizer

Cons

  • Short warranty
  • Not durable
  • Very bright blue light on unit is distracting
  • Not a True HEPA filter

2. Envion Therapure TPP220-M

The Envion Therapure TPP220-M is a compact air purifier, rated to cover only 70 sq. ft. of space. This air purifier is ideal for use on desktops or bedside tables where it can be as close to your breathing space as possible. It uses a permanent HEPA-type filter, a photocatalyst filter, and a UV light.

The most obvious problem with this unit is that it covers a much too small space. At best, this unit should only be used for individual use. Also, because of its affordable price, you can’t expect the TPP220-M to have many features or even a True HEPA filter.

All things considered, however, the TPP220-M is a good desktop air purifier for people looking to cover their personal breathing space or just a tiny room. It’s easy to use and has a very small footprint that would allow it to go unnoticed at home. As an added bonus, it’s available in a variety of vibrant colors.

Pros

  • Affordable (upfront and long-term)
  • Compact, lightweight
  • Easy to use and maintain
  • UV light acts as a germicidal
  • Comes in a variety of colors
  • No need for filter replacements

Cons

  • Small room coverage
  • Not many features
  • Not a True HEPA filter
  • Short warranty

3. Envion Therapure TPP50

The Envion Therapure TPP50 is Envion’s only plug-in air purifier, capable of covering 115 sq. ft. of space. Unlike the other air purifiers, this model is an ionic air purifier which means it only relies on generating negative ions to clean the air. These negative ions attach themselves to airborne particles such as dust.

Because it’s only a plug-in air purifier, the TPP50 is limited to only having a small room coverage and no smart features whatsoever. Furthermore, it only relies on negative ion generation to clean the air and doesn’t use any other type of air purification method.

However, as far as plug-in air purifiers go, the TPP50 boasts above average performance and is reliable enough for some homeowners just looking to remove light odors and some dust. The compact, lightweight, and affordable TPP50 is also ideal for travellers who want to get clean air on the go.

Pros

  • Affordable (upfront and long-term)
  • Compact, lightweight
  • Easy to use, plug-and-play type
  • No need for filter replacements as it does not use filters

Cons

  • Small room coverage
  • Not many features
  • Relies only on negative ion generation
  • Short warranty

4. Envion Therapure 220H

Another air purifier from Envion’s Therapure line is the 220H. Rated to cover 210 sq., the 220H makes use of a permanent HEPA-type filter and a UV germicidal lamp to purify the air. This type of air purifier doesn’t take too much space and is ideal for small to medium-sized rooms.

One obvious flaw with this model is that it does not use a True HEPA filter, only a less efficient HEPA-type filter. Furthermore, its specifications and features are not as impressive as we’d like. Of course, for an air purifier this cheap, this doesn’t come as a surprise.

What we do like about this unit is that it’s affordable, low maintenance, easy to use, and is a great, entry-level choice for homeowners looking to try air purifiers for the first time.

Pros

  • Affordable (upfront and long-term)
  • Covers small to medium-sized rooms
  • No need for filter replacements
  • Easy to use and maintain
  • Small, lightweight

Cons

  • Low CADR ratings
  • Not many features
  • Not a True HEPA filter
  • Short warranty

Buyer’s Guide:

Envion Therapure Air Purifier

Advantages of Owning Envion Therapure Air Purifiers

  • Affordable

    One of the main advantages to owning an Envion Therapure air purifier is that it is often very budget-friendly, making it ideal for those strapped for cash or those who don’t want to invest too much on an air purifier.

  • No replacement filters

    Envion Therapure air purifiers feature permanent HEPA filters and photocatalyst filters which only need to be cleaned regularly, rather than be replaced. This makes Envion Therapure air purifiers affordable both upfront and long-term.

  • Robust air filtration system

    Despite their modest price tag, Envion Therapure air purifiers don’t skimp on air purification tech and features. As evidenced by their specifications, Envion Therapure air purifiers use a variety of technologies to keep the air in your home clean, including HEPA filters, photocatalyst air purifiers, ionizers, and UV light.

Disadvantages of Owning Envion Therapure Air Purifiers

  • Doesn’t use True HEPA filters

    True HEPA filters are one of the best — if not the best — when it comes to filtering out a majority of air pollutants like pollen, pet dander, dust mites, and mold. HEPA-type filters like the ones Envion air purifiers use are usually significantly less efficient when compared to True HEPA filters.

  • Relatively small room coverage

    Compared to other air purifiers available on the market, Envion Therapure air purifiers tend to cater to small to medium-sized rooms only.

  • Fewer features

    Due to its affordable price, it’s not surprising that Envion Therapure Air Purifiers lack desirable features such as air quality indicators, filter clean indicators, auto modes, and more. However, they do feature timer features.

How to Care for Permanent HEPA filters

Permanent HEPA filters are built more durable than conventional HEPA filters that are replaceable. This means that they can withstand washing and cleaning procedures. Typically, permanent HEPA filters are cleaned using a vacuum cleaner at least once a week to ensure that the filter remains efficient. However, it’s always best consult the unit’s instruction manual first!

Frequently Asked Questions

How effective are permanent HEPA-type filters?

HEPA-type filters are typically capable of removing up to 99% of particles as small as 2.5 microns in size. For the most part, yes, HEPA-type filters are effective against larger particles. However, they pale in comparison compared to True HEPA filters which can remove 99.97% of particles as small as 0.3 microns in size. Most air pollutants — like allergens and bacteria — are much smaller than 2.5 microns which means that these tend to go through HEPA-type filters.

Is it safe to use ionizers around children?

Ionizers are generally safe to use. However, the primary concern with ionizers is that they produce ozone as a by-product. Ozone is a lung irritant and can aggravate pre-existing respiratory diseases. While the levels of ozone tend to be very low and heavily regulated by local governments, ionizers still do produce ozone. With that said, we’d recommend not using it around children.

How does a photocatalyst filter work?

A photocatalyst filters are usually used in combination with a UV light. The filter has a layer of titanium dioxide on the surface and when the UV light hits the surface, the reaction releases negative electrons. The electrons react with water molecules in the air to create hydroxyl radicals which attack carbon-based pollutant molecules, turning them into harmless substances.

Final Thoughts

Envion’s Therapure line is one of three that the brand has developed over the years, with the other two being Ionic Pro and and Allergy Pro. The Therapure line is their most well-rounded line, combining the key characteristics of both the Ionic Pro and Allergy Pro lines.

We highly recommend the Envion Therapure TPP240-M. At such an affordable price, you get a medium-room air purifier with an extensive air filtration system capable of removing a variety of air pollutants ranging from miniscule allergens to harmful disease-causing bacteria.
