Buying guide: Things to consider before buying the best ozone air purifiers

Before buying the best ozone air purifiers, you have to consider certain aspects. Otherwise, the buyer may be the wrong one! But you shouldn’t be disappointed! Here we are providing you with some valuable tips. We guarantee if you follow them properly, you must be successful in this regard. Let’s have a look:


The certification is an essential factor you need to consider. You will find two labels on the product package. The Energy Star logo is one of them. The air purifiers with this certification need 40% less energy than others. As a result, they are energy-efficient, and you need to pay less electric bills for that. 

AHAM Verified seal is another one I was talking about. It means that the home appliance manufacturers association has already examined the machine. And that is why the machine has clean air delivery rates which are popularly known as CADRs. Also, you will find the guidelines for room size there. The device having a CADR of 250 means it can clean 250 cubic feet per minute. 

An air purifier with a higher CADR can work quicker. For this reason, we always recommend our customers buy a device having HEPA filters. Conveniently, they often come out with the highest CADR rates. 

Filter replacement cost

Usually, you need to replace pleated filters within a year and activated carbon filters within three months. Most of the devices include an indicator that will signal or tell you when to replace the filters. However, you will get a variety of filters on the market. And the price of them is also different. Of course, not all the filters are suitable for a machine. Hence, you should buy one which is compatible with cheap-rated filters. It will lower the filter replacement cost. 


Before buying the best ozone air purifiers, you must consider the range capacity. Otherwise, it can be a mere wastage of money. For example – you need an air purifier for a 1200 square feet apartment. But the machine you have bought has only 800 square feet range capacity. What will you do then? Won’t it be useless? That is why we always suggest measuring your space first and then buying according to that. 

Work silently or noisy

An air purifier may have a high-performance. But it doesn’t mean that you will be happy with it. What will happen to you if it produces unbearable noise? Certainly, the situation will be painful! So you have to check it carefully. For this reason, we are advising you to buy one that has 20 decibels of noise rating. It will not spoil your sound sleep!
