Buyer’s Guide

Humanity is evolving and so is a technology and the machines that we use. There is more that is making the air that we breathe today dirty. It is only fitting that we also use technology to clean it out. 

But the air is not only made dirty by cars or outside gases and fumes, mold in our homes, odor from when we cook, and pet dander, are some of the ways that the air in our homes is made dirty. 

An air purifier will clean the air for you and provide you with better quality. However, not all air purifiers were created equal. They have different features and this makes them distinctly different from each other. 

Why should I get a filterless air purifier?

If you have given even a second thought to buying an air purifier, it also means that you have had to think about filters and the role that they play in the air purifier.

There are some things that make a filterless air purifier a good buy, like how they are virtually silent. This is something that is high up on the list of priorities. They also save you quite a dime because you will not need to be changing the filters ever so often.

Filterless purifiers differ slightly according to the manufacturer. However, some features are common across the board, as their ability to clean the air. Some purifiers are great at removing smoke, whilst others do a better job of dealing with mold. 

It may seem like it is virtually impossible to have an effective air purifier, that does not have a filter. Air purifiers that do not have the help of a filter, use ionizers. 

It uses two electronically charged plates and releases anions into the air, where they will attract allergens and even the smallest particles. These particles are then collected by the second plate which acts almost like a magnet, stopping the spread of harmful airborne toxins. 

Some air purifiers make use of an electrostatic precipitator air purification system. Thi system is also very effective in trapping harmful particles. The air is electrically charged and this helps to clean the air. 

Air purifiers that do not have filters are great for many reasons, including efficient cleaning of the air. The disadvantage though, is that these filters are not as effective as purifiers that have HEPA filters.

The other issue is that ions emitted into the air by filterless purifiers can also emit ozone. It is not all manufacturers that see to it faithfully, that this does not happen. 

What should I look for in a good filterless air purifier?

It is important that you do your fair share of digging around when you are buying an air purifier that does not have a filter. Make sure that you understand how the purifier works. Also, check on the room coverage that the purifier can handle. This will guide you to buy the appropriate size. 

Another feature to check for is how it is connected to a power source. Also, check on the controls and how easy they are to understand. Purifiers with WIFI connectivity have an edge because this also means that you can get updates for the unit online, and you also have remote access, especially if it has a mobile app.

Check with the manufacturer, and see how friendly the purifier is on the environment. The emission of ions can sometimes go hand in hand with the emission of ozone which is not good for the environment. However, there are some units that have made this a point. Avoid any purifiers that emit ozone. 

Also, check on what it specializes in cleaning. Some purifiers are better at cleaning certain particles, and not so great at cleaning some particles. Make it a point to find a purifier that specializes in removing the particles that you want to remove. This is what will make a particular unit, efficient or not for you. Decide what you want it to do for you. 

Also, check on certifications and how safe it is for you medically. Some brands are synonymous with quality. Look out for user reviews and know which manufacturer is known for making the best air purifiers. 

You may also want to look out for the design and color that you can get the purifier in so that it is in with everything else in your space. There are hundreds of different designs that you can choose on. The important thing is to cross-reference what you need versus what you are getting. 

Another feature to think about is whether or not there are indicators on the purifier. These will help you know when there is a need to pay attention to any part of the purifier. Also, check on the power consumption and make sure that it is something that you can sustain. 

You also want to make sure that you know about every part that may need to be replaced so that you are not caught by surprise. One of the reasons filterless purifiers are so popular now is because you do not need to replace filters. But it is important that you know if there are any other parts that will need to be replaced and what the potential cost will be.
