Therapure Air Purifier Reviews Guide

Within the Envion Therapure air purifier line up, there are six popular models:

And we can group these models into two categories:

  • Medium to Large Size Rooms (TPP440, TPP240, TPP230, TPP220)
  • Small Rooms and Personal Spaces (TPP100, TPP50)

We’ll start by reviewing the four medium to large size air purifiers, then move onto the two smaller models.

That way, you can get a fair comparison between each Therapure air purifier.

In each section, we’ll go over all of the important details you need to know to make a well-informed decision as well as offers some recommendations on which model will work best for certain needs.

Therapure Reviews: TPP440, TPP240, TPP230 & TPP220

One of the most impressive things about Envion is that they’ve created a Therapure air purifier for multiple size rooms and budgets.

This means you can get the exact air purifier you need to meet your specific requirements.

We’ll first look at the similarities between that each of these four Therapure models has in common.

Similarities Between Each Model

Graphic of germs

No matter which of the larger air purifier models you choose (TPP440, TPP240, TPP230 or TPP220), you’ll get a high-quality device that’s guaranteed to help remove these harmful particles from the air:

  • Allergens
  • Pollen
  • Germs
  • Bacteria
  • Viruses
  • Smoke
  • Mold Spores
  • Odors

You’ll also find that all of these Therapure air purifier models contains a similar set of features, including:

Filter Types

  • HEPA-Type Filter — This is a permanent filter that never needs to be replaced (saving you money). Just vacuum it clean when it gets dirty. It captures pollutants down to 0.1 microns in size (invisible to the naked eye).
  • Ultra Violet Light — This technology destroys germs, bacteria, viruses, and mold spores so the air around you is sterile and clean.
  • Photocatalyst Filter — This removes dangerous gases and toxic volatile organic compounds from the air, such as paint fumes; household chemical vapors; and gases that leak out of building materials, carpeting, and furniture.

Fan Speeds

Each of these air purifiers also includes 3 fan speeds so you can adjust the power of the device up or down as you see fit.

Air Changes Per Hour

Air Changes Per Hour or ACH indicates how many times an air purifier can exchange the full volume of air inside a room every hour.

These Envion Therapure air purifiers have a 3X ACH rating. This means that every 20 minutes the air is fully cleaned with these devices as long as they’re used in a room that doesn’t exceed the intended total square footage. (Those numbers are explained in the next section.)

Envion already gives you the ACH rating, but if you’re curious about how this number is calculated, then check out our guide on how to calculate ACH.


Due to the low weight and tower design of these models, you can easily take them from room to room with you.

Differences Between Each Model

At their core, each Therapure air purifier cleans the air the same way; however, there are some minor differences in the features as you go up in the model numbers.

Those specific differences include:

The TPP220 and TPP230 models are pretty basic without a lot of advanced capabilities.

As for the TPP220:

  • It has a manual dial to control the fan speeds.
  • It covers up to 210 square feet (sq. ft.) which is good for the smaller end of medium-size rooms (e.g. bedrooms, dens, home offices, etc.).

See TPP220 Reviews on

  • Like the TPP220, it also has a manual dial to control the fan speeds.
  • It covers up to 350 sq. ft. which makes it good for medium to larger size rooms (e.g. large bedrooms, living rooms, apartment living areas, etc.)

See TPP230 Reviews on

Our Recommendation on the TPP220 vs TPP230

Choosing between the Therapure TPP220 and TPP230 shouldn’t be a tough decision. If you’re going to use the air purifier in a small room, get the TPP220. If you have a larger room, get the TPP230.

Once you hit the TPP240 model number and higher, you start getting more advanced and user-friendly options.

  • It has touch buttons for all controls.
  • It has an LED display on the top showing you which controls are active.
  • It includes a 24-hour timer that you can use to automatically shut off the unit at a certain time.
  • It has a filter clean indicator that alerts you for when it’s time to clean the filter.
  • It includes an optional ionizer function to boost the air cleaning power. This charges air particles to make them easier to trap in the HEPA filter.
  • It covers up to 343 square feet (sq. ft.) which makes it good for medium to larger size rooms (similar to the TPP220).

The TPP440 has a slight design change from the TPP240 model, most notably the carrying handle on top and the front panel display.

  • It has touch buttons for the controls like the TPP240.
  • It has an LED display but it’s on the front, not the top like the TPP240.
  • It includes a 24-hour timer like the TPP240.
  • It has a filter clean indicator like the TPP240.
  • It includes an extra night mode function that turns the lights off on the unit. This is good for sleeping.
  • It covers up to 395 sq. ft., making it a bit more powerful than the TPP240 to handle larger rooms.
  • It doesn’t include an Ionizer. That feature was removed in this model.

Our Recommendation on the TPP240 vs TPP440

As you can see, the Therapure TPP240 and TPP440 are quite similar.

Aside from design differences, the main thing you need to ask yourself if you’re considering either of these models is, “Do you want the extra ionizer function and slightly smaller room size coverage that comes with the TPP240 or would you rather have a bit more coverage at the expense of removing the ionizer?”

If it were us, we’d pick the Therapure TPP240 for the extra air cleaning ionizer function. But, only if the room we were using it in was less than 350 square feet. Otherwise, we’d have to choose the TPP440 for optimal air cleaning coverage.

Therapure Reviews: TPP100 & TPP50

These last two Therapure air purifier reviews won’t be a very long section.

The fact is that these air purifiers are made for small rooms and personal use.

Inside and out, they’re quite different, so we can’t compare them directly to each other. However, we can give you an overview of how each one works and who would benefit the most by them.

The TPP50 is a compact air purifier without a cord. It doesn’t use a HEPA filter at all but two other types of technology to clean the air.

As for the exact features, you get:

  • A pluggable air purifier that fits in any standard wall outlet. This makes it portable and easy to take with you when traveling.
  • It uses electrostatic filter strips to collect airborne contaminants. These are permanent and reusable for the life of the product. It’s suggested that you clean them every two weeks.
  • It includes an ultra violet light to kill bacteria, viruses, and germs that flow through the system. This creates sterilized air that’s healthier to breathe.
  • It covers up to 115 sq. ft. which is great for personal spaces (e.g. small bedrooms, bathrooms, kitchen, etc.)
  • There are no fan speeds or dials to control. You just plug it in and it goes to work purifying the air.

The TPP100 is a micro HEPA air purifier. It’s good for stripping airborne pollen, dust, pet dander, and other common allergens from the air.

As for this model, you get:

  • A 360° HEPA-type filter that draws air in from all sides. It’s permanent and can be vacuumed clean.
  • 2 fan speeds for you to choose between: high and low.
  • Coverage up to 115 sq. ft. (the same amount as the TPP50)

See TPP100 Reviews on

Our Recommendation on the TPP50 vs TPP100

If you’re not sure which air purifier model to choose, the TPP50 versus TPP100, consider these two points:

  • The TPP50 kills airborne germs. If that’s important to you, choose this model.
  • The TPP100 is more efficient at trapping allergen and dust particles because it has a HEPA-type filter. The TPP50 doesn’t have HEPA material to trap particles but rather “magnetizes” them to small strips. If those particles are a concern to you, choose the TPP100.
