What is an air purifier?

An air purifier is a device that helps clean up your indoor air quality by removing household particles from the air. You can think of an air purifier as a miniature version of the ventilation system used in commercial buildings where as many as 10 filters work to keep the air indoors clean and fresh.


How do air purifiers work?

There are three different types of air purifiers, namely mechanical, ionizing and electronic.

Mechanical filters are made up of a porous material that traps particles in the air. The most common type of mechanical filters are known as HEPA (High-Efficiency Particulate Air) filters which are very effective at trapping bacteria, pollen and other large pollutants in your home.

Ionizing purifiers use an electric current to trap pollutants in an electrically charged grid. These grids can also be found in air ionizers which work by emitting ions into the air that bind to particles and hold them until they are washed away.

Electronic purifiers use a fan to suck up room air and pass it through electronic plates that trap pollutants. The downside of this type of purifier is that it is less effective at removing persistent odours.


What should you look out for before buying an air purifier for your home?

Size of the room – the bigger the room, obviously, the more coverage you’ll get. You should be able to find a small enough air purifier for pretty much any size room though.

Room shape and dimensions – some rooms have odd dimensions that might make it impossible to place an air purifier in a particular area. Take the time to measure and see what you can work with.

Purifier type – There are tons of air purifiers out there and each one is designed for a different purpose. Determine what you need the most in an air purifier and go shopping from there.

Price – This is probably one of the most important factors, especially if you’re buying an air purifier online. You want something that’s not going to break the bank but does the job well enough.


What are the benefits of an air purifier?

Besides helping to remove pollutants from your air, air purifiers also provide other benefits. One of the main benefits they provide is that you will be able to breathe clean and healthy air in your own home. Also, most purifiers today come with an air ionizer which has antimicrobial properties that help clean the air.


What are the drawbacks of an air purifier?

Unfortunately, there are some drawbacks to using air purifiers at home. For one, they often require regular maintenance and filters need to be replaced after a certain period of time. As well, some older models may require you to place them in the middle of your room which can be disruptive. Finally, air purifiers are also fairly expensive and higher-end models can run for thousands of rupees (though there are some that fall on both sides of this price range).


What pollutants can air purifiers prevent?

Air purifiers are effective at removing many different kinds of pollutants. One example is cigarette smoke, which contains over 4,000 different kinds of harmful chemicals. Other examples include pollen, pet dander, dust mites and mold spores.


Frequently Asked Questions on Air Purifier

1. How do HEPA filters work?

HEPA stands for “High-Efficiency Particulate Air.” It’s a type of filter used in some types of air purifiers and it’s a very effective way to remove the smallest pollutants. Typically, HEPA filters are constructed from layers that trap pollutants between each layer.


2. What pollutants are most commonly found in the home?

Dust is one of the most common pollutants in homes and workplaces, but others include pet dander, pollen, mold spores, household chemicals and cigarette smoke.


3. How do I know if my air quality is bad?

If you suffer from allergies, asthma or other respiratory problems, it’s likely that your air quality isn’t so great. You might notice symptoms like a stuffy nose, coughing or sneezing when indoors at home. You may also have decreased energy or increased fatigue.


4. What should I do if my home air quality is poor?

The first step in improving your home’s ventilation is to examine the HVAC system in your home, including the following – heating and cooling units, vents/ducts, registers and fans. Cleaning these components regularly will help improve your air quality.


5. Why do I need a HEPA filter?

Air purifiers with High-Efficiency Particulate Air (HEPA) filters are great for families with allergies or small children since they can keep 99% of allergens from passing through the filter. If you have pets, a HEPA filter is also an excellent choice.


6. What is the best air purifier for me?

There are many things to consider when looking for an air purifier for your home. The first thing to think about is how big of an area you want to cover. Many models come in different sizes that are more or less effective at purifying larger areas. Also, if you suffer from allergies or asthma, make sure to check the air purifier’s CADR (Clean Air Delivery Rate), which is a key measure of how effective it is at filtering out particles. Other things to consider are the types of pollutants you want to be filtered, how often you will need to replace filters and what maintenance (if any) the air purifier requires.


7. How long should an air purifier last?

A good air purifier will generally come with a 1-year warranty which indicates the expected life of the product under normal use. However, there are some things that can affect the lifespan of your machine and reduce its performance over time. Make sure to readjust your air purifier’s settings if you move it from one area to another since pollutants can vary widely by location. It would also be a good idea to check the warranty on your product and consider replacement parts if necessary.


8. Do air purifiers reduce allergy symptoms?

In some cases, yes! An air purifier is an excellent addition to any home with allergies or small children who suffer from allergies. In fact, some studies even show reduced symptoms in people who don’t have allergy problems.


9. What is a germicidal UV lamp?

Germicidal UV lamp contains UV-C radiation that kills germs and bacteria on contact. Because of this, it’s a great choice for people who suffer from allergies or asthma.



Air purifiers are a great way to improve your home’s air quality by removing contaminants and allergens. If you’re looking for an air purifier, it’s important that the filter is High-Efficiency Particulate Air (HEPA) filters or else all of the pollutants will get through. You should also make sure that there is some kind of UV light integrated into your machine so you can kill bacteria on contact. Finally, be mindful when moving the device from one area in your house to another because different areas have varying levels of pollution.
