Choosing an air purifier shouldn't be based solely on the coverage area advertised by the manufacturer. In 2026, CADR, the type of filtration, the number of air changes per hour, and the cost of filters are among the most useful criteria for comparing devices.

For people with allergies to pollen, dust mites, pets, or dust, we recommend choosing a unit with an effective HEPA filter and a CADR high enough for the room.

Quick Response

For a small room, a compact unit like the Protech P1211 may be sufficient.

For a medium-sized room, the Protech P3001 offers a CADR of 310 m³/h.

For allergies and large rooms, the Protech P6006 offers a rated CADR of 510 m³/h, HEPA H13 filtration, and multiple filtration stages.

The Dupray Bloom stands out primarily for its design and Canadian manufacturing, while some models, such as the Blueair Blue Pure 211i Max, emphasize a particularly high airflow rate. Honeywell and Levoit models also remain popular choices in Canada.

The CADR: Probably the Most Important Number to Watch

The CADR, or Clean Air Delivery Rate, indicates the amount of air effectively filtered by the purifier over a given period of time.

A unit may be advertised as having a capacity of “1,500 sq. ft.,” but that figure doesn’t mean much if the manufacturer doesn’t specify how many times the air in that room is actually filtered each hour.

For someone with allergies, we generally prefer a system that provides several air changes per hour rather than one that treats the entire volume of the room only once per hour.

Example

A 400-square-foot room with a ceiling height of about 8 feet requires approximately:

A CADR of 450 m³/h to achieve approximately 5 air changes per hour.

Here's an order of magnitude:

*Approximate value based on a ceiling height of about 8 feet.

That's why it's important not to base your choice solely on a statement such as "covers up to 1,000 or 1,500 sq. ft."

HEPA, True HEPA, and HEPA H13: What's the Difference?

The term HEPA refers to a high-efficiency filter designed to trap very small particles in the air.

These particles may include, among others:

• pollen;
• animal dander;
• particles from dust mites;
• fine dust;
• certain mold spores;
• some of the particles present in the smoke.

A HEPA H13 filter corresponds to a particularly high filtration class according to the European standard EN 1822.

The Protech Allergies P1211, P3001, and P6006 models use H13 HEPA filters.

The Dupray Bloom also uses an H13 HEPA filter.

But be careful: an excellent filter with low airflow isn't necessarily the best choice.

When it comes to allergies, you need to consider both at the same time:

Filter quality + CADR appropriate for the room.

---

Which air purifier should you choose if you have allergies?

For respiratory allergies, we would prioritize testing for:

1. True HEPA filtration

It captures the fine particles responsible for many allergic symptoms.

2. A sufficiently high CADR

The faster the unit processes the air in the room, the faster the particle concentration can decrease.

3. A prefilter

This is especially useful with pets, since it traps hair, pet fur, and large dust particles before they reach the HEPA filter.

4. Activated carbon

It is particularly useful when you also want to reduce odors, smoke, and certain gaseous pollutants.

Our choice for a bedroom: Protech P1211

The P1211 is the smallest air purifier in the Protech Allergies line.

It offers:

CADR: 120 m³/h
Filter: HEPA H13
Activated carbon: yes
Pre-filtration: yes
Current price: $212.50

It is best suited for a bedroom, a small office, or a small enclosed space. Protech currently recommends a floor area of approximately 215 sq. ft.

We would choose it because:

a bedroom, an office, or as a second air purifier in the house.

[See the P1211 air purifier]

---

Our pick for a medium-sized room: Protech P3001

The P3001 strikes a balance between size and power.

CADR: 310 m³/h
Filter: HEPA H13
Washable pre-filter: yes
Activated carbon: Yes
Current price: $510

Protech currently recommends it for areas of up to approximately 645 square feet, depending on the desired air change rate.

We would choose it because:

a medium-sized living room, a workspace, or a particularly large bedroom.

[See the P3001 air purifier]

Our Protech recommendation for allergies and large rooms: P6006

The P6006 has the highest CADR rating in the Protech Allergies line:

510 m³/h

It combines:

• H13 HEPA filter;
• prefiltration;
• activated carbon;
• PM2.5 particle sensor;
• automatic mode;
• humidity and temperature display;
• additional filtration;
• UV function (can be enabled).

Its current specifications indicate a CADR of 510 m³/h and a stated coverage area of up to 1,076 ft².

However, for someone who is highly sensitive to allergens, we recommend not automatically setting the coverage area to the maximum. A P6006 used in a smaller room will provide more air changes per hour.

We would choose it because:

people with severe allergies, a large living room, an open-concept space, or a clinic or office that requires high airflow.

Blueair Blue Pure 211i Max: one of the highest CADR ratings in this comparison

The Blue Pure 211i Max is particularly impressive when you look solely at the volume of air it treats.

Blueair currently states:

CADR for smoke: 435 CFM
CADR for dust: 452 CFM
Pollen CADR: 450 CFM

Blueair recommends approximately 674 square feet at 4.8 air changes per hour and specifies a noise level of 23 to 53 dB.

So, what's the best air purifier in Quebec?

There isn't a single air purifier that's the best in every situation.

For a bedroom: Protech P1211
For an average-sized room: Protech P3001
For allergies and high flow rates at Protech: Protech P6006
For the design: Dupray Bloom
For a particularly high CADR: Blueair Blue Pure 211i Max
For a traditional brand and a True HEPA filter: Honeywell HPA300C
For smart features in an average-sized room: Levoit Vital 200S

For someone with allergies, we would place greater emphasis on the actual CADR, HEPA filtration, and the number of air changes per hour than on the maximum coverage area listed on the box.

Frequently Asked Questions

Which CADR should you choose for an air purifier?

The required CADR depends on the volume of the room. The larger the room, the higher the CADR must be. For people with allergies, multiple air changes per hour are generally preferable to a single air change.

Is an H13 HEPA filter better for allergies?

An H13 HEPA filter has very high filtration efficiency. However, the filter only does part of the work: the air purifier must also circulate enough air through the filter.

Does an air purifier remove dust mites?

Dust mites live mainly in bedding, mattresses, carpets, and upholstered furniture. Therefore, an air purifier cannot eliminate dust mites from a mattress.

However, it can reduce the amount of dust particles and dust mite allergens that become airborne.

For a dust mite allergy, it is best to combine air purification with dust-mite-proof covers and other environmental control measures.

Which air purifier should you choose for wildfire smoke?

When it comes to smoke particles, look primarily for a high CADR and effective filtration of fine particles.

Activated carbon is also effective against certain odors and gaseous pollutants associated with smoke.

Is it better to let your air purifier run continuously?

In most cases, yes. An air purifier works only on the air that passes through its filter. Continuous operation—especially in automatic mode or at a low speed when the air is clean—helps maintain more consistent filtration.
