Compare our air purifiers

The objectives of a purifier are numerous: to purify your interior; to eliminate fine particles, pollen, and pet allergens; and to rid your home of volatile organic compounds such as gases and odours.

We have selected well-known, top-of-the-line products from reputable brands to provide a fair comparison of each purifier and their main features.

All device information has been collected from the websites of each brand; when something is missing, we do not present anything.

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

The next questions concern the type of filter used in the air purifier. Is it a true HEPA filter? What particles does it filter? What additional filters, if any, does it have?

Any model of air purifier must include several filters to ensure a high level of filtration, not only of fine particles but also of volatile organic compounds – that is, gases and odours.

Ideally, an air purifier should be composed of an antimicrobial pre-filter, a HEPA filter, and an activated carbon filter.

Are there any additional devices which, in addition to the filtration, can improve the efficiency of the air purifier?

Finally, how easy is it to use? What has been done to make it 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?

Does your product have a night mode enabling it to continue filtering pollution from your room without disturbing you? There is also the purchase price to consider. You should evaluate the quality-price ratio and the cost of acquiring replacement filters. This is to ensure that the total cost of operating and using the air purifier is well known. On this page you will find all the technical information relating to a number of top-quality potential devices. But listen carefully to customer reviews, and beyond the design of the devices, check which tests are performed on each purifier before making your choice. Also make sure that the necessary functions are available on the system and that its quality level is good, so that its primary function – removing pollutants, fine particles, and allergens – is properly fulfilled. Each section describes the main features of the device and the parts to look out for in any air purifier model. Filter: for air purifiers, a true 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 microns. 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 pollens, pet allergens, mould spores, bacteria, and others. The filtration level of these filters is so fine that they are able to filter out viruses such as H1N1 and coronavirus. There are several levels of HEPA filters depending on the efficiency with which they filter out fine particles such as PM¬2.5 (particles that are 2.5 microns or less in width). A HEPA filter’s price will vary relative to its level of filtration efficiency, as well as the maximum area from which it is capable of effectively eliminating pollution. The larger the filter, the larger the surface area treated. The quality level of the HEPA filter is an excellent indicator of the quality of the device. Philips, Rowenta, and Dyson do not communicate their filters’ filtration levels. Activated carbon or charcoal filters: these absorb gases and odours. Treated with oxygen that opens millions of tiny pores, these filters absorb volatile organic compounds (VOCs) like gases, chemical fumes, and odours. 370 grams of activated carbon will have a total effective 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 odours in rooms and houses. It is this filter that will absorb the pollution linked to chemical products such as formaldehyde, ethers, and solvents. Beyond odours, this filter will protect you from the types of pollution which has a direct effect on health. The quality of your device will therefore also depend on the volume of activated carbon present in the filter. An air purifier must necessarily have an activated carbon filter and its efficiency, in your home or office, is directly linked to its volume. Easy to use Plug-and-play delivery: when you receive your Protech Allergies air purifier, just take it out of its box, plug it into the electrical outlet and press start. That's it! There's no need to worry about setting up the filters and other preparation work. Neither Philips, Rowenta, nor Dyson offer this ease of use on their models. Noise level: it is important to make sure that in normal operation the noise level of the air purifier does not bother you. Be careful, decibels evolve according to a logarithmic scale, which means that a 3 dB increase means the sound volume has doubled. Your appliance should be as quiet as possible when in use, otherwise it will become a nuisance. All our purifiers are equipped with several operating speeds. Ideally, at low speed or in night mode it should not exceed 18-20 decibels. Automatic mode: the particle detector pilots the air purifier automatically. Night mode: reduces the brightness of indicator lights and deactivates the fine particle detector to keep the air purifier at its minimum speed and at the lowest sound level. This is very important if the air purifier is installed in a bedroom. Child lock: Prevents children from being able to change the settings. Easy filter replacement. It's a simple operation with no risk of releasing dust and other pollutants into your room. Customer reviews can be a good indicator of the quality of products and services offered by the air purifier device. The total cost of ownership over time. This is the purchase price of the device combined with the cost of replacing the filters over its lifetime, and it must be reasonable! At Protech Allergies, our replacement filters are not expensive. Moreover, we maintain our prices over time. How do I choose the right air purifier for my needs? 1) For individuals and professionals: - Airborne diseases: do you or any of your family members or employees suffer from allergies, asthma, or other diseases? - Environment: is your environment polluted and at what level? - Pets: do you have cats or other pets? - Room size: the type of air purifier should be chosen according to the size of the room to ensure effective purification. - Finally, take note of customer reviews, which are a good indicator of the quality of the device, its efficiency, and its operating mode. They will also tell you the overall service level of the company. - How easy is it to order and replace the HEPA filter and carbon 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 have to be carefully chosen to be well adapted. - Does your activity produce microparticles or dander? The quality level of the purifier will be chosen to effectively sanitize your work area. - Do you or your staff suffer from allergies, headaches, rhinitis, or conjunctivitis? - Room size: the type of purifier must also be chosen according to the size of the room to ensure effective purification. - Working environment: the air purifier must be as quiet as possible to avoid becoming a nuisance. - Price and operating costs: installation, power consumption and the price of consumables should be low and controlled over time.
