What are air purifiers?

These are devices or appliances which have been designed to ensure airborne pollutants are removed from homes and offices. Their major function is to ensure that there is an improved quality of air around such environments. They have been produced to help people that have health challenges such as asthma, allergies and breathing difficulties.


What does CFM stand for?

CFM stands for cubic feet per minute. This measurement represents how many cubic feet of air move through the unit per minute. This is important when considering which air purifier is right for you. The higher the CFM, the better potential air purification results.

Keep in mind that CFM can be impacted by a variety of factors, including fan speeds, insulation, air flow in the room, furniture in the room, and the amount of pollutants in the air. However, there is an equation to help you determine an ideal CFM, which can provide help when deciding on air purifiers.

To find your ideal CFM, calculate the total volume of your space (length x width x height in cubic feet) and divide this number by your desired ACH. Below is a sample equation:

CFM  =

18 ft x 24 ft x 8 ft

Do I need an air purifier?

Just as said above, air purifiers have the major function of ensuring the quality of air in your home or office is improved. The truth is that there are lots of air pollutants around such environments that you may not be aware of. Once they are ignored, your life is at risk given the threats they can pose to your health.


Furthermore, it has been discovered that the quality of air indoor is worse when compared to the one outdoor. The former can contain pet dander, smoke, dust, and others. Some of the reasons why you may want to embrace the idea of using an air purifier are: it can help you fight against the effects of smoke from cigarettes, breathing with ease around the home, combating problems related to frequent skin rashes, itchy or dry skin and many others.


A major environmental issue in various parts of the world today is indoor pollution. Your health is always at risk once such a problem is ignored. It is even worse when there are kids and elderly persons in such house.


How do air purifiers work?

These devices have been designed in such a way that they can effectively draw polluted air from any given space. Such air will then be made to pass through different stages of filter. In other words, they contain internal fans which help in pulling the air via various filters. This is how harmful particles such as bacteria, pollen and dust are removed from the air.


Once the filtering process is completed, the air will then be circulated again in the room through the air purifier. In a nutshell, air purifiers ensure that polluted air goes through various processes to become clean and healthy again in a room.


How can I identify the best air purifier?

It is very important to know that air purifiers are of various types in the market. This could be in terms of producers, cost, features, and many other factors. For instance, there are air purifiers which can only help to filter the smoke from cigarettes. Also, there are air purifiers that can help to filter bad odors from your home. In case you are suffering from asthma, it is recommended to go for a device that can filter dust.


It all depends on what you need. In other words, try to analyze the problems you want an air purifier to solve. Also, consider the size of your budget as you will also need to spend money on maintenance of such device in the long run. These could be on replacement of filters.


Don’t air purifiers produce noise?

This is one of the reasons why most people are yet to purchase air purifiers in their homes. They are of the opinion that such devices generate too much noise. This isn’t true as there are some which are silent even while working. They can only start producing noise once you decide to increase their speed.


Generally speaking, the noise produced by air purifiers is minimal. It can be compared to what fans produce. This means it isn’t as serious as you must have imagined. In case you want an air purifier to produce less noise, ensure to adjust its settings to the lowest or medium.


How often should air purifiers be used?

It is important to note that air purifiers have been designed to be used regularly. Most people switch theirs off at some point which isn’t good. The only time these devices can be switched off is when you aren’t around. This is the only way they can help to improve the quality of air in your home. Once you ever get it switched off, dust will find its way into the house and this can be dangerous. The bottom line is that your air purifier should always be working.


Is it expensive to use an air purifier?

This is another situation where the answer lies within the differences among air purifiers. Some are much more energy efficient than others. HEPA air purifiers typically consume 30 to 200 watts of electricity.

To put this into perspective, a lamp uses approximately 60 watts and a computer uses 365 watts. Using an air purifier probably isn’t going to impact your electricity bill tremendously.

However, if this is a top concern in your search for an air purifier, consider an Energy-Star rated air purifier or find out how many watts an air purifier actually uses before purchasing it.


How can I know the size to purchase?

There are different sizes of air purifiers in the market. The starting point is your room since it will give you an idea of the type that can fit in perfectly.  If your room is big, avoid purchasing any of those small air purifiers. Also, note that most of the devices in the market can only be installed in one room at a time. It means they are not meant to serve an entire building.


In other words, there should be an air purifier in every room. Ask the seller for help in case you are still confused about which one should be bought. Most of them will be willing to explain how you can go about solving such challenge.
