The stated aims of a purifier are always numerous: to purify your home. Eliminate fine particles, pollen and pet allergens, but also clean your home of volatile organic compounds such as gases and odors.

We've selected well-known, top-of-the-range products from reputable brands to give you a fair comparison of each purifier and its key features.

All the information on the devices has been collected from each brand's website, so where something is missing, we've left it blank.

What are the most important criteria for comparing air purifiers? Firstly, the Clean Air Delivery Rate (CADR) which is a major quality feature, defining the maximum room size that an air purifier can purify.

Then there's the type of filter used in the air purifier: is it a true HEPA filter , what particles does it filter and what additional filters are available?

All air purifiers need to include several filters to guarantee good filtration quality, not only for fine particles, but also for volatile organic compounds such as gases and odors.

Ideally, an air purifier should include an anti-microbial pre-filter, a hepa filter and an activated carbon filter.

Are there any additional devices that, added to the filtration, can improve the air purifier's efficiency?

Finally, what has been done to make the air purifier as user-friendly as possible?

Are the filters easy to replace? Is the unit quiet enough to purify your room without becoming a nuisance?

Does your product have a night mode to continue filtering pollution from your room without disturbing you?

Then there's the purchase price, to assess value for money and the cost of acquiring replacement filters. This is to ensure that the total cost of running and using the air purifier is well known.

On this page, you'll find all the technical advice you need on your appliance. But listen carefully to customer reviews, and beyond the design of the devices, check which tests are carried out on each purifier before making your choice. Make sure that the necessary functions are available on the system and that its quality level is good, so that its primary function of eliminating pollutants, fine particles and allergens is fulfilled.

Each paragraph describes the main features and parts to look out for in any model of air purifier.

Filter: for air purifiers, a guaranteed HEPA (High Efficiency Particulate Air) filter is the gold standard.

True HEPA filters are recommended by organizations such as the EPA, the U.S. Environmental Protection Agency, the American Lung Association and the American Academy of Pediatrics, Allergy and Immunology.

These filters force air through a very fine membrane, and can filter out and retain over 99% of particles as fine as 0.3 micrometers .

HEPA filters are highly recommended for use in air purifiers, as they are the most effective filters for filtering and blocking very fine particles such as pollen, pet allergens, mold spores, bacteria and fine particles in general. The filtration level of these filters is so fine that they are able to retain even the largest viruses, such as H1N1 and coronavirus.

There are several levels of HEPA filters, depending on their percentage efficiency in filtering fine particles such as PM 2.5. The price of a HEPA filter depends on its level of filtration and its ability to eliminate pollution in a room of varying size. The larger the filter, the greater the surface area treated.

The quality of the HEPA filter is an excellent indicator of the quality of the appliance. Philips, Rowenta and Dyson don't all communicate on filtration levels.

Activated carbon or charcoal filters: absorb gases and odors

Treated with oxygen that opens millions of tiny pores, these filters absorb volatile organic compounds (VOCs) such as gases, chemical fumes and odors.

370 grams of activated carbon will have a total surface area of 243,000 m².

The use of activated carbon is a major complementary compound for the efficiency of filtration systems against pollution, gases and of course odors in a room and inside the home. It is this filter that will absorb pollution linked to chemical products such as formaldehyde, ethers and solvents. Beyond odors, this filter will protect you from this type of pollution, which has a direct effect on your health. The quality of your device will therefore also depend on the volume of activated carbon present in the filter.

An air purifier must have an activated carbon filter, and its effectiveness in your home or office is directly linked to its volume.

Ease of use

Delivered plug and play: when you receive your air purifier, simply take it out of the box, plug in the electrical socket and press start. That's all there is to it! There's no need to worry about setting up filters or any other preparatory work.

Neither Philips, Rowenta nor Dyson offer this ease of use on their models.

Noise level: it's important to make sure that the air purifier's noise level doesn't bother you during normal operation. Note that decibels evolve on a logarithmic scale, which means that 3 db more is equivalent to doubling the sound intensity.

Your appliance must be as quiet as possible during operation, otherwise it will become a nuisance. All purifiers are equipped with several operating speeds. Ideally, at low speed or in night mode, it should not exceed 18/20 decibels.

Automatic mode with a particle detector that controls the air purifier automatically.

Night mode: reduces brightness, deactivates the fine particle detector to keep the air purifier at minimum speed and at the lowest sound level. Very important if the purifier is installed in a bedroom.

Child lock: prevents children from changing settings.

Easy filter replacement. It's a simple operation with no risk of releasing dust and other pollutants into your room.

Customer reviews are a good indicator of the quality of the products and services offered by each air purifier model.

Total cost of ownership over time.

This is the purchase price plus the cost of replacing filters, and it must be reasonable!

At Protech Allergies, our filter replacement costs are low. What's more, we maintain our prices over time.

How to find the right air purifier for your needs?1) For home and professional use:

- Airborne ailments: do you or those around you suffer from allergies, asthma or other illnesses?

- Environment: is your environment polluted, and to what degree?

- Pets: do you have cats or other pets?

- Room dimensions: the type of air purifier should be chosen according to room dimensions to ensure perfect purification.

- Finally, take a look at customer reviews: they're a good indicator of the device's quality, efficiency and mode of operation. They'll also tell you about the company's general level of service, and whether the model is quiet when purifying and sanitizing your indoor air.

- How easy is it to order and replace the HEPA filter, the charcoal filter?

2) For professionals:

- Work environment: do you use chemicals, do you have a waiting room with potentially contagious patients? Do you treat organisms likely to transmit bacteria and viruses? Filters will need to be carefully selected to ensure that they are suitable.

- Does your activity produce micro-particles or dander? The quality level of the purifier will be chosen to effectively sanitize your workroom.

- Are you or your staff prone to allergies, headaches, rhinitis or conjunctivitis?

- Room dimensions: the type of purifier should also be chosen according to room dimensions to ensure perfect purification.

- Work environment: to avoid becoming a nuisance, the air purifier must be as quiet as possible.
