Things to Consider

How much do you know about Therapure air purifiers? It is obvious that they clean the indoor air and reduce pollutants and other harmful compounds. But how to choose a unit that is the most efficient in doing that? In this section, we are focusing on giving you more information about these products. Our team focused on factors to consider when choosing an air purifier. The FAQ section covers some questions that the community often asks to upgrade knowledge about these devices.

What are Therapure air purifiers best against?

Allow us to let you in on a little secret about Therapure air purifiers – they are versatile and capable of reducing various harmful compounds.

If you choose a Therapure triple-action purifier, it can deal with the following:

Allergens and pollutants – this includes dust and pollen to cigarette smoke, pet hair and dander, and even mold spores.

Bacteria and germs – the range goes from mildew and fungi to bacteria and viruses.

Fumes and odors – any unpleasant odors, indoor air pollutants, toxic and household chemicals’ fumes, and chemical emissions from the new carpet will be reduced if you use air purifiers.

It is crucial to mention that coverage area and efficiency vary depending on the unit. However, they may remove asthma triggers and help you to breathe better. They also work on reducing the risk of lung disease by removing cigarette smoke, potentially dangerous asbestos particles, and promote overall health.

How to pick the best Therapure air purifier

Air purifiers are products with many different features, which is why you shouldn’t make a rash decision when choosing a device. You should assess different factors, including filtration, coverage area, portability, etc. We are focusing on the main features of these purifiers in the section below. If you are looking to choose a product that perfectly fits your needs, it is vital to follow the guidelines mentioned in our advisor. The best air purifier is the one that meets your expectations, which means you should consider what you need from this device first.

Coverage area

The first thing to consider is the area where you plan to use an air purifier. It would be great if you can measure the exact surface planned for purifying.

Envion specifies the coverage area of each Therapure air purifier in its description. You will find the area a product can cover with maximum efficiency, and the largest surface it can purify with satisfactory results. Small units will cover anywhere from 25 to 120 square feet, and standard air purifiers should be enough for rooms from 200 to 400 square feet.

Your task is to compare the surface of your room with the coverage area of the device. If you have a particularly large room or want to improve results, you can buy two purifiers to use in the same area.

Fan speeds

The majority of Therapure triple-action air purifiers come with adjustable fan speeds. Some only have a single setting available, while others come with multiple adjustments. For example, the Therapure TPP440 allows you to choose between three-speed options. That makes the device more convenient to use because you can pick different settings for different rooms.

For instance, you can use the air purifier at maximum settings when you have guests that are smokers. Once they leave, you can adjust to low speed to minimize power consumption while keeping the air clean. Fan speeds are directly related to noise levels. These devices are noisier at higher speeds, which is why you should consider picking the lowest setting when you head to bed.

Clean air delivery rate

The clean air delivery rate is described in product descriptions as a CADR rating. You will find separate ratings for each of the following categories:

  • Pollen
  • Dust
  • Smoke

The higher the CADR rating, the more efficient the purifier is. However, please note that device size will affect its efficiency. You cannot expect a small purifier to have an extremely high CADR rating. That is why compact units, such as the Therapure TPP50, might have CADR at approximately 30 per category, which is fine for smaller rooms, while premium devices, like the Therapure TPP230H, will go over 120.

The efficiency of an air purifier can also be considered based on its coverage area. The manufacturer specifies the surface that a product can cover with maximum efficiency, as well as area size where you can expect decent results.


Where do you plan to keep your air purifier? Do you have plenty of space available for the device, or you need a unit with a small footprint?

If you are looking for a product that will fit in any corner, you should consider a Therapure TPP240 tower air purifier. It has a compact footprint, and the only thing to ensure is that it can fit height-wise.

Those who plan to keep their devices at desks should consider desktop air purifiers, such as the Therapure TPP100. If you want a product that is easy to move around in your bag, go for the Therapure TPP50 mini air purifier that can fit into your hands.


Size goes hand in hand with weight, and both factors contribute to portability. The lighter the product is, the easier it is to move it around. If you need an air purifier to use in different rooms or apartments, it is vital to consider its portability. That is why you should look for the lightest unit out there.

Keep in mind that smaller air purifiers might not perform as well as the standard-sized products. That is why you should find a ratio between performance and portability that best fits your needs.


Filtration is a crucial factor when choosing an air purifier. It is a component that determines how well the product captures particles that may affect the quality of air.

The majority of Therapure air purifiers, including the premium Therapure TPP440, use a high-quality permanent HEPA filter. Thanks to that, you don’t have to replace your filters frequently. However, you will need to clean them regularly to maintain optimal performance. Fortunately, the device will indicate when the filter needs vacuuming.

HEPA filters are of exceptional quality, but even they won’t last forever. Their lifespan can be several years, but if you notice that the air doesn’t seem as clean as before, it may be wise to replace them.


Envion is a reputable brand that has been on the market for a long time and established itself as the leader in the industry of air purifiers. No matter which unit you choose, you can expect a reliable product that will serve you for a long time.

The manufacturer confirms that with a one-year limited warranty on all products. It is a fine indicator that the company trusts in its devices. The chances are that they will last longer than the warranty specifies. If you want to maximize their lifespan, it is vital to maintain the unit properly and avoid damaging it in any way.

Extra features

Extra features are all those bells and whistles that improve the performance and experience of using a product. You may consider looking for a Therapure air purifier with UV lights and a UV/VOC switch. That helps you to maximize versatility and optimize the performance of the unit at any moment. For instance, the Therapure TPP240 has that feature.

Other extra features to consider include:

Ionizer – by ionizing the air, it will be easier for the device to capture airborne particles, which improves the efficiency of the device.

Timer – some units, such as the Therapure TPP440, come with a timer that allows you to program the product in advance.

Display – having a display is useful because it indicates all relevant information related to the unit’s performance.


How much noise do Therapure air purifiers produce?

The manufacturer doesn’t specify the exact noise level of the devices, but be aware that some air purifiers can get a bit loud. That is especially true if you are using a product at its highest speed settings. For example, if an air purifier has three fan speeds, the fastest one may cause a bit of noise. You will probably get used to it after a while, but it can be a problem when you head to bed. Fortunately, you don’t have to turn off the purifier. Instead, go with a low-speed setting, and the product will become a lot quieter than before.

How should I clean Therapure air purifiers?

The majority of Therapure air cleaners use a permanent HEPA filter. That simplifies the cleaning process, but please note that you should clean the filter regularly. Whenever the product warns you to vacuum the filter, make sure to do it ASAP.

First, turn off the unit and unplug it from the power outlet. Once you confirm that the device is unplugged, disassemble the unit and remove the HEPA filter. Use a vacuum to clean it and place it back in the product. Don’t use any water, soap, or detergents on the filter. However, you can feel free to use soap and damp cloth on the outer components of the device.

Do Therapure air purifiers help with allergies?

Do you hate spring because you have pollen issues? If you are dealing with allergies outside, they shouldn’t be a problem indoor. Air cleaners can be of great assistance when dealing with allergies. You want to go with a product with the best possible filter and maximum efficiency for the area where you spend time.

The Therapure TPP230H has an impressive coverage area that can purify the air in medium and large-sized rooms. This and other units designed by Envion can remove allergens and pollutants like pet dander and hair, pollen and dust, cigarette smoke, etc. If you are looking for added efficiency, choose the Therapure TPP220-M germicidal air purifier that can also deal with germs, bacteria, and toxic fumes.

Our Verdict

Ultimately, we can only confirm that the Therapure TPP440 can be an excellent choice for all those looking for exceptional air purifying results. An impressive CADR rating and triple-action purification make this a truly all-around unit to clean indoor air. The product even comes with extra features like a 24-hour timer and an LED screen.

The Therapure TPP240 is another great pick that can purify the air and save you some money by reducing the initial investment. The product comes with an ionizer and timer, but it is the permanent HEPA filter that makes it the most attractive.

If you are looking for an ample coverage area, go for the Therapure TPP230H. It maintains maximum efficiency at 234 square feet, which is very impressive.

We hope that this information was helpful, and now you can find the best Therapure air purifier. The final choice is up to you. Make sure to consider aesthetic and performance features and ensure they are in line with your expectations. That is a guarantee that you will maximize the product’s benefits and enjoy clean air for a long time!
