10 Best Air Purifiers for Allergies and Asthma

Did you know that your house can be squeaky clean yet full of allergens that trigger allergies and asthma? Let me explain.

Although you clean your home regularly, there is one thing you overlook: the air. The air inside your home is full of dust, smoke, household odor, and other allergens. In fact, according to the Asthma and Allergy Foundation of America (AAFA), the level of pollutants indoors is two to five times higher than outdoor levels

So, what should you do?

Along with dusting, cleaning the surfaces, and keeping the room ventilated, you can use an allergy air purifier. You know, those appliances that use filters and fans to remove allergens and other particles and circulate clean air back. Using an air purifier makes sure you breathe fresh air.

Here is the deal, though: not all air purifiers are designed the same. Don’t buy just any purifier. You need a purifier that is specially made to eliminate asthma and allergy-causing agents.

How do you tell the best air purifiers for allergies and asthma?

Please read on, and you will learn all about it. We have reviewed ten of the best air purifiers for asthma and allergies. Highlighted some of the factors you should consider when choosing the best air purifier for your condition. We shall also look at the connection between allergies and asthma.

What is the connection between Allergies and Asthma?

Asthma and allergies are two of the most common persistent diseases worldwide. According to experts, these two conditions often occur together and are known to cause respiratory symptoms such as airway congestion and coughing. However, each condition has specific unique symptoms.

Allergies may cause the following symptoms:
  • Itchy and watery eyes
  • Sneezing
  • Running nose
  • Hives and rashes
  • Itchy throat
On the other hand, asthmatic people do not experience the above symptoms. Asthma causes:
  • Tightens of the chest
  • Breathlessness
  • Wheezing
  • coughing

Factors to Consider When Choosing the Best Air Purifier for Asthma and Allergies

1) Coverage area

The coverage area refers to how big a room can be purified by a particular purifier model given its capability and capacity. It is essential to know the size of the place you want to purify because coverage area varies depending on the model.

So how do you determine the size of your room?

Let’s revisit our lessons, shall we? Don’t fret, its simple grade four mathematics.

Using a tape measure to measure the length and the width of your room. Then multiply the two.

Let me explain further.

If the length of your room is 4square feet and the Width is 3 square feet, it will be 4*3= 12square feet. (Told you, simple mathematics)

When choosing the best air purifier, check the specifications, and ensure it can cover your home. We recommend you chose one that has a slightly higher coverage.

2) HEPA Filter

The type of filter used by a purifier is critical. When shopping, choose a model that has HEPA Filtration technology. It is best for allergies and asthma.

HEPA stands for High-Efficiency Particulate Air. This filtration technology is known for removing even the smallest of particles and allergens.

HEPA collects particles using a highly dense paper filter. The filter traps the particles, stopping them from recirculating into the room, thus clean air.

3) CADR

The best way to measure an air purifier’s capacity is by its Clean Air Delivery Rate (CADR). CADR is the quantity of the cubic meter per minute that a purifier can effectively purify.

Since different allergens cause different reactions, purifiers can have different CADR specifications. They may have ratings for dust, pollen, and smoke.

For the best air purifier for allergies and asthma, a purifier with high ratings on dust and pollen is the best.

4) Noise Level

Although noise doesn’t cause allergies or asthma, it is important to choose a purifier with a low level of noise. You know, one whose operational level doesn’t interfere with a conversation.
