Factors to Consider When Buying the Best Air Purifier

The Air Quality

One of your main considerations when buying the best air purifier for your home is the quality of air in it. If your main problem is cigarette smoke, then look for products that have activated carbon filters and ionization functions. Activated carbon is the most absorbent filter material there is and the best in eliminating smoke, which is one of the hardest odors to get rid of.

If you are suffering from the effects of allergies or asthma, the best air purifier for your home should have true HEPA filters. Just make sure that what you are getting uses TRUE HEPA filters as opposed to HEPA-type filters.

If you need an air purifier primarily to eliminate or reduce odors, then an air cleaner that uses oxidants, ozone or carbon will be your best bet. Negative ion-only air purifiers are not the most effective at eliminating strong odors, so choose those with oxidants or ozone that are effective in destroying most odor-causing particles and carbon that removes them from the air.

The Room Size

You need to know the size of the room that you are going to use the air purifier that you are getting. An air purifier cannot purify an entire home or office building alone, regardless of how many square-feet it claims to cover. When buying an air purifier, make sure that the device fits your total room space.

You can get the square footage of your room by measuring the length and width of the treatment area in feet and multiplying the two numbers together.

Operating Costs

There are air purifier models that use filters that are replaceable. Filter prices can range from around $10 each up to about $100, so before buying the best air purifier for your home, take a close look at the filter that you will be using. Typically, you need to replace the carbon filters every three months, while the main filter needs replacement once a year.

Also, it is also important to find out how much your air purifier will cost in power consumption; this is important as some can cost over $300 per year in electricity. Add these all up to check if what you are getting is something that you will be comfortable with spending money on.

Noise Level

This is especially important if you want to use the air purifier while you sleep or work. Some of the more effective air purifiers can produce quite a noise, so be careful in choosing one. You may want to visit a physical store to personally see and hear if the air purifier you are getting will let you sleep or work in peace.

Check Reviews and Feedbacks

It is very advisable to view online reviews of the air purifier that you are eyeing. You can actually get useful information from people who have used the products for a longer time. There are many other factors you should consider, but reading the feedbacks can go a long way in helping you make an informed decision.


Choosing the best air purifier for your home or office can be a daunting task. You do not regularly hear about HEPA or CADR, so you are not expected to know about these things. This list will help guide you in buying the best.

For us, the best overall air purifier is the Coway AP-1512HH Mighty Air Purifier as it has wonderful features that are effective in cleaning the air—the ionizer function, the several levels of filtration, and many others.
