People don’t often take air pollution seriously because we’ve been use to the polluted air around us for a long time. While we take serious concern about the purity of water we drink by installing water filters and purifiers, air quality is something that isn’t given serious thought. Air pollution is caused due to various factors including the chemicals from factories, emission from cars and other vehicles, dust and pollen etc. Even if you live in an area free from factories, your home can still be polluted if you have pets and common dust particles.
Households are susceptible to particle allergens like pollen, mold, and dander, and this is where installing the best air purifier will help give you pure and fresh air to breathe. In this article, we’ve rounded up some of the best air purifiers on the market along with a lot of useful information that will help you in choosing the best air purifier for your home.

What is an air purifier?
An air purifier is a machine that helps in purifying the air you breathe in your house by removing all the harmful contaminants in the air. If you have pets in your house, then you should seriously consider buying an air purifier in your house. Because your pets attract a lot of harmful pollutants, the more your pet moves around your home, the more your chances of having polluted air increases. Air purifiers not only purify your air from harmful contaminants and pollutants, they also help in removing all the uncomfortable odors to provide you with fresh air to breathe.
How do air purifiers work?
Air purifiers generally work by forcing the air using a fan into a filter array where all the contaminants and harmful particles are trapped and only letting pure air flow in your house. However, removing the pollutants doesn’t mean the air is 100% purified because air could also contain various harmful gases and organic compounds that could pollute your air. Some air purifier models also come with filters and absorbents to remove these harmful gases from the air.
Things to know before buying an air purifier for your home
When it comes to air purifiers, they come in various sizes and price ranges on the market. Similar to other household products, the products that are highly effective are expensive, but one thing you need to remember is the more you pay for a product, the less you spend on its operating and maintenance costs.
How can air purifiers help you?
Air purifiers that come equipped with HEPA or other equivalent filters help in removing all the harmful particles and contaminants from the air. Even though many claim to feature HEPA filters, only purifiers that comes with true HEPA filters can effectively purify the air. High Efficiency Particulate Air (HEPA) is a standard where filters adhering to HEPA guidelines will purify your air to almost 99.7%. And when you have fresh air circulating in your house, it automatically helps in improving your sleep quality, prevents all kinds of allergies, asthma, and other diseases and issues related to polluted air.
Remember, however, that HEPA filters are not designed to catch those harmful gases in your air, so you may still need to invest in an additional absorbent to remove it from the air. Air purifiers also don’t remove all larger-sized allergens like pet hair and dust mites. And since there is every chance of pollutants entering your house every time you open the door or a window, the air purifiers need to be run continuously to keep the air purified inside your house all the time.
Energy Usage and Replacement Filters
One of the important aspects that keeps an air purifier running is its filter, and it needs to be replaced regularly to keep your air purified effectively. It’s for this reason air purifiers are not considered to be a one-time investment. Another major aspect in providing pure and fresh air throughout your house is that it could increase your electric bill as well. Hence before purchasing an air purifier, it’s best to take a look at the energy use and the costs involved in replacing the filter etc. Take into account the kilowatt-hours the air purifier utilizes every day and just multiply it with the prevailing electricity rates in your city to predict the amount of electricity the purifier can use.
Size and placement
Another important aspect when choosing an air purifier is that you need to select a model that sits well in your house. A general rule is that unlike water filters, you cannot install an air purifier against a wall because it needs to take in air from all side to provide better results. If you room is small, better go for a compact one that suits your budget and your requirements.
The market is filled with a lot of air purifier models, and every brand is trying to outperform the other by introducing new features with every release. Try to look for models that come with added features like timers, sensors, or options to slow down the purifier when the air quality is at the desired level.

Air Purifier FAQs
How to improve air quality in your home
If you’re looking to improve the air quality in your home, then the best option is to invest in an air purification system. Even though you use vacuum cleaners to get the dust and dirt from your carpets, they may still hold smaller dust and pollen particles that may become dangerous for your health over a period of time. A good air purifier with HEPA filters can help in removing all kinds of contaminants and pollutants and give you fresh, clean air to breathe all the time.
Do CADR scores measure gas-based pollutants?
The CADR rating doesn’t give you a measurement of gaseous pollutants, but the representation of the capability of an air purifier to purify the air inside your home.
Is the air more polluted inside or outside your home?
While many think that air outside of your house is more polluted, that’s not always the case. If you have pets or smoke inside, the air quality can be around 3-5 times more contaminated with pollutants than the air quality outside.
Does size matter?
Yes, the size does matter as the larger the size, the better it serves a larger area. But remember, air purifiers that cover a larger area are more expensive than compact ones.
