Allergies can be a real pain, and they make you sneeze, wheeze, and feel like your head is stuffed full of cotton all the time. If you don’t get your allergies under control, they can wreak havoc on your life. Coughing, headaches, and congestion can make you miserable. Untreated allergies can also lead to many other illnesses, such as ear infections and sinus problems.

There are different types of purifiers available today, each claiming that it is best for your needs. But there are some features that you must look for when choosing an air purifier for dealing with allergies.

You may find different filters in air purifiers like activated carbon filters, ozone generators, ionizers, and HEPA filters. Among these filters is the HEPA filter, which works effectively by removing allergens from the indoor air. The tiny particles trapped by this filter include dust.

The first thing you have to do is identify what causes allergies in your home environment. It could be dust particles or pet dander or mold spores, and so on. Even cooking fumes and smoke from cigarettes can also cause allergies. The next step is choosing an air purifier with HEPA filters to remove these allergens from the indoors effectively. Suppose you have asthma or another similar lung disease. In that case, you should look for a model with activated carbon filters for removing volatile organic compounds (VOCs) from the air inside your house.

HEPA Filters-air purifier for allergies?

Consider buying an air purifier that comes with HEPA (High-Efficiency Particulate Air) filters which remove 99.97% of the indoor air pollutants from the indoor air that are 0.3 microns in size. These filters can be used for more than two years before replacement. The indoor air contains many tiny particles that can trigger allergic reactions.

HEPA air purifiers come with a dense filter that cleans the matted fibers to trap dust and dirt particles. The air purifiers use three different mechanisms of Impact, Interception, and diffusion to trap the pollutants in the indoor air.

HEPA filters reduce allergic reactions, help people with asthma breathe more efficiently, and improve overall health by removing harmful contaminants from the indoor environment.

If you suffer from allergies or asthma, HEPA is more important than ever. Regular air purifiers do not capture many of these particles passing through their filters. As a result, opening a non-HEPA unit can cause symptoms to flare up!

What do you want to filter?

Air purifiers come with various options. Whether you want purifiers with HIPA filter, ion filter, or UV air filter, every filter has unique features.

As per the research, carbon filters are not good at removing pollen, dander, dust, and mold, but they help get rid of particles and odors in the air.

I have a chart that will help you decide what type of filter you need based on what you want to filter.

Types of air filtersHow they work and what they target
High-efficiency particulate air (HEPA)pulpy media air filters remove particles from the air.
Activated carbonActivated carbon removes harmful gases from the air.
Ionizeran ionizer uses a high-voltage wire or carbon brush to remove particles from the air. The negative ions interact with the air particles, causing them to attract to the filter or other objects in the room.
Electrostatic precipitationSimilar to ionizers, this uses a wire to charge particles and bring them to the filter.
Ultraviolet germicidal irradiation (UVGI)UV light inactivates microbes. This doesn’t pull out the microbes from the space — it only inactivates them.
Photoelectrochemical oxidation (PECO)The Photoelectrochemical oxidation (PECO) new technology helps to remove small particles in the air with the photoelectrochemical reaction that removes and destroys pollutants.

Based on CADR. What is the Clean Air Delivery Rate?

The Clean Air Delivery Rate (CADR) is important to consider when looking for an air purifier. A rating above 350 m3/ hour is excellent for purifying indoor air. CARD counts the air cleaner’s effectiveness according to room space and volume of clean air produced per minute.

In other words, the CADR tells you how quickly an air purifier works to clean the air in your home. So if you’re looking for a fast-acting purifier, look for a high CADR number.

Based On the area, you want to filter.

Choosing the right size air cleaner for your home can be a challenge. Select Accordingly to the size of your room, the number of allergens in it, and the amount of time you spend in it.

Think about how you use your space. Remember that these figures are based on using the machine at its highest speed or noisiest speed. For less sound, you may want to have a unit capable of effective cleaning when running at less than its maximum blower speed.

This may be sufficient for your needs, but a larger unit in the same room can produce more air changes per hour, thus decreasing particle levels by 90% or more—the correct target in medical situations. The CADR comes in use, and they recognize the number of particles and square feet an air purifier can reach, so go for high CADR.
