Envion is now just a brand name under the North America Boneco, but this brand is still very popular in the U.S market. Of course, you don’t get the direct support from Envion team anymore, and you won’t hope this brand to bring more new air purifiers as well as updates. Still, as the entry-level of the sixth generation Therapure air purifiers, the Envion Therapure TPP620 still catches enough attention. Let’s check it out in our Envion Therapure TPP620 Review.

Envion Therapure TPP620 Price

With all Envion air purifiers are now under the name Boneco, it’s no surprise that this Swiss air purifier company is using them on strengthening their low-budget range as they previously don’t manufacture any devices for this segment.

The Envion Therapure TPP620 was the first air purifier of the sixth generation, following up by the Envion Therapure TPP630 and Envion Therapure TPP640. It is also the equivalent with the Envion Therapure TPP220.

The official price tag of this Envion Therapure TPP620 is higher than the ancient entry-level, however, as it is $119. In fact, it is near the price tag of the Envion Therapure TPP230, which is supposed to have higher performance.

At this price, it is an obvious competitor with the TruSens Z-1000, GermGuardian AC4300 and GermGuardian AC5000. These tower air purifiers come with an UV-C light filter, just like our today Envion Therapure TPP620, however, they are more available.

Envion Therapure TPP620 Design and Size

The Envion Therapure TPP620 starts a prominent design for all of the Therapure air purifiers later, something that you can imagine as a tower speaker. However, I don’t deny that it is a lot more premium than the older Therapure TPP540 and Therapure TPP440. It is designed for the modern times.

It isn’t too smaller than its big brothers, with the height of 22 inches and the width of 7.5 inches. In fact, it makes the Envion Therapure TPP620 slimmer than many air purifiers in Therapure lineup, so it’s more suitable for any small rooms. This alongside the tower design means you can take it anywhere in your home, especially with the built-in handles and a weight of only 8.2 lbs.

And like any common tower air purifiers in the past, the Envion Therapure TPP620 uses the back-to-front air flow system concept. As you can see, the air outlet is made like the front of a speaker, so it has large grill to deliver more clean air.

On top of the Therapure TPP620, there is only one knob to change fan speeds, as well as an only button for UV-C light feature.

Envion Therapure TPP620 Filters

As a rule of thumb, we check the quality and quantity of air filters to decide the performance of one air purifier, as well as the air filter types. Envion Therapure TPP620 covers a 4-stage air cleaning system, which is better than the ordinary Therapure TPP220.

1. Pre-filter – First is a cleanable pre-filter, which can help remove the hair, fur and large dust in the air.
2. HEPA-type filter – It is not a True HEPA filter, and the quality is much inferior. It is able to capture mold, smoke, germs, bacteria, viruses, common allergens, pet dander & odor from the air in your home.
3. UV-C light filter – The Envion Therapure TPP620 can kill germs, bacteria and viruses with the UV lamp. It is certified by California Air Resources Board (CARB) for ozone emissions under safety.
4. Photocatalyst filter – A material to support the UV light filter in removing dangerous gasses and toxic Volatile Organic Compounds (VOCs) from the air.

Well, this could be the original air cleaning system of a typical Therapure air purifier, combining both HEPA filter and UV-C light to both trap and kill the allergens. The process is even better with an extra use of Photocatalyst, to completely kill any biological pollutants.

Because I’ve only got the Envion Therapure TPP620 and Therapure TPP630 recently, I made a new test for these Therapure air purifiers, in a room of 150 square feet, within 1 hour. The Envion Therapure TPP620 was near the efficient with the old Therapure TPP230 in the past, scored 90% of trapping any particles down to 0.3 microns. Well, it is below the more expensive Envion Four Seasons FS200 in terms of air filtration, and it is nowhere near the performance of the modern air purifiers like Vornado AC350, Vornadobaby Purio or Levoit Core P350.

Envion only recommends to vacuum the the air filter, and they even said that the filter is permanent to use. Below is the deal for its filter replacement.

Envion Therapure TPP620 Room Coverage

The manufacturer-suggested room size of this Envion Therapure TPP620 is 300 square feet, which is the same as many other Therapure air purifiers.

The ACH of Envion Therapure TPP620 is 3x. It can exchange the air in your room every 20 minutes.

The CADR of Envion Therapure TPP620 is 124 Dust/ 116 Smoke/ 140 Pollen (cfm). It is quite lower than any old models like Therapure TPP220 or Therapure TPP230.

Envion Therapure TPP620 Sound

It seems noise level is a very out-of-control problem for any old air purifier models, just like the Envion Therapure TPP620. You should know that this air purifier was released at the same time as the GermGuardian AC5000, but Envion doesn’t keep the noise down as better as the Guardian Technologies.

The tested noise level of this Envion Therapure TPP620 is 62 decibels (db), which is clearly higher than even the flagship Therapure TPP640. For an air purifier with such low fan power, this noise level is unreasonable.

Envion Therapure TPP620 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” because we need to run an air purifier for a constant long time, and power consumption is really a thing to consider.

The Envion Therapure TPP620 isn’t rated as an Energy Star air purifier, but it has the same power consumption as the certified Therapure TPP640. I’ve measured the rated power of this air purifier to be 60 watts.

Running an Envion Therapure TPP620 for 8 hours per day, and you need to pay $22 each year.

Envion Therapure TPP620 Additional Features

It’s time we get back to the common “additional features” section for any low-end Therapure air purifiers. Besides an UV control button and a knob, you won’t find anything fancy for the Envion Therapure TPP640. If you are looking for any high-end features, I recommend you to check the Okaysou AirMax8L, Rowenta Intense Pure Air PU4020 or Airthereal APH260 instead.

You want such feature on an Envion product? Then you must pay for $150 more to have the flagship Envion Therapure TPP640. But is it worth such investment?

Envion Therapure TPP620 Customer Service

Envion is a subsidiary of the Swiss brand Boneco, a big air purifier brand with exceptional customer service. You can call the support for any Envion products toll free at 800-875-8577. This is the quickest way to reach the customer service, but if you prefer email, their contact is customerservice@envionproducts.com.

You will only enjoy the warranty for the first year since purchase date, and you need to pay for any shipping and processing fee that occur. 1-year warranty is not as good as many other big brands (even Boneco own products have better warranty policy), but it is still better than nothing, right?

Our verdict

The Envion Therapure TPP620 is old, and you can’t select it even though you really love the brand. It only has a HEPA-type air filter, its fan power is weak but the noise level is absurdly high. Perhaps, it’s time for the end of Envion air purifier products.
