Air Purifier Buying Guide

Did you know that air inside your home in the UK can be up to five times more polluted as compared to the outside air? Most people do not pay attention to the quality of air inside even when they spend most of their time indoors, either at home or in office.

Creating a healthy environment goes beyond just washing the floors and keeping your walls and ceiling clean. You also need to pay attention to the quality of air inside your home and if the quality is not up to the mark, you need to invest in the right air purifier.

An unhealthy indoor environment is typically full of pollutants such as particles from cooking, wood-burning, tobacco, pet dander, pollen as well as volatile organic compounds from paints, cleaning products and adhesives among others. Pollutants up to 10 µm in size such as those found in dust and smoke are of greater concern as these can get deep inside your lungs. If you keep breathing in air full of such particles, it might aggravate lungs and lead to asthma attacks. In fact, long-term exposure to polluted indoor air full of such particles/pollutants has been associated with reduced lung function, bronchitis and in some cases, even premature death.

Key Takeaways

  • Indoor air in the UK can be up to five times more polluted than outdoor air, making air purifiers essential for improving indoor air quality.
  • Air purifiers come in various types, such as HEPA, ionic, carbon, and UV purifiers, each with its own method of removing pollutants from the air.
  • When buying an air purifier, consider factors like HEPA technology, area coverage, dimensions, weight, noise, design, smartphone app connectivity, multi-functionality, and guarantee to ensure you get the best value for your money while improving air quality in your home.

What is an Air Purifier?

Air PurifierAir purifiers are appliances that remove microscopic particles from the air around you in an enclosed space. By removing these pollutants or bad particulates from the air you breathe, these appliances allow you to breathe in pure air. It is especially useful for people suffering from respiratory illnesses.

Even if you do not have any respiratory issues, you will still find an air purifier to be of great help as a good quality purifier is capable of removing almost 99% of pollutants in the indoor air. It will allow your lungs to function better and you should notice a dramatic improvement in your overall health once you have a good air purifier in the room where you spend the most time.

What Are the Different Types of Air Purifiers?

Some of the common types of air purifiers based on size include desk air purifiers, tower air purifiers, portable air purifiers and oscillating air purifiers among others.

The basic function of different types of air purifiers remains the same. These pull in the air full of pollutants and release clean air.

The desk models are compact in size and designed to be kept on a shelf or desk. These are less powerful as compared to bigger machines but can play an effective role in cleaning indoor air in small rooms. The tower models are tall in shape and typically, powerful enough for large spaces. There are also large portable models that are usually powerful and designed to clean air in large spaces. The oscillating models rotate while running. There are also some models that also double up as fans.

Air purifiers are also classified based on the filters and process used for removing the pollutants or microscopic particles from the air.

One of the most popular types is the HEPA air purifier. It has HEPA filters that are great at catching microscopic particles typically associated with causing allergies. Another type is an ionic air purifier. These emit electrically charged ions that attach onto the allergens and dust particles which helps in removing them from the air. There is also the carbon air purifier. It has a carbon filter that is helpful in getting rid of smoke, vapours and odours from indoor air. The UV air purifiers use ultraviolet light for breaking down floating bacteria and airborne viruses.

How Does an Air Purifier Work?

All the air purifiers have fans that pull in the indoor air. This air is then cleaned with the help of filters inside the purifier and cleaned air is then released into the room. An air purifier needs to run continuously for several hours in order to effectively bring down the level of pollutants in the indoor air.

In case of HEPA air purifiers, the filters are capable of trapping particles that are more than 0.3 µm in size. Air purifiers with HEPA filters are excellent at removing almost all the pollutants in the air in an enclosed space.

Air Purifier FilterIn case of ionising purifiers, corona discharge method is used for charging molecules. An intense electrical field is created inside the air purifier and it gives a negative/positive charge to the molecules passing through. Bigger particles in the indoor air such as contaminants and dust are usually charged and get attracted to these charged molecules. The metal plates within the purifier then attract these particles and remove them from the air.

Some ioniser models also generate ozone. Ozone is formed by splitting off the oxygen molecules. However, there is serious doubt about the effectiveness of ozone generators. In fact, ozone is a toxic gas and it reacts with other chemicals. It is also capable of oxidising metals leading to corrosion. Therefore, it is recommended to stay away from ozone generating air purifiers.

In carbon air filters, activated charcoal is used as an adsorbent. It is an extremely porous substance that is capable of trapping larger molecules. In case of UV light purifiers, the UV light bathes the air passing through which helps in getting rid of airborne bacteria and viruses.

What Are the Benefits of an Air Purifier?

If you’re still wondering whether you need an air purifier, here’s a list of some of the major benefits of buying one.

  1. As mentioned in the beginning, indoor air can be up to 5 times dirtier and an air purifier will make sure that you and your family members always breathe in clean air.
  2. Get rid of unpleasant odours with a good quality purifier. If you like to cook or you are facing odour issues in your home, bringing in an air purifier will help in getting rid of those unpleasant odours.
  3. If you have pets in your home, a high quality air purifier will help you get rid of any airborne allergens typically released by pets such as fur, pet dander and other airborne allergens.
  4. If you have a fireplace or someone in your family smokes, bringing in an air purifier can help in getting rid of the smoke particles.
  5. A high quality air purifier will help in trapping dust particles before they have a chance to settle down. In simple terms, you will have less to clean.
  6. Good quality purifiers are capable of getting rid of up to 99.97% of all the airborne bacteria and viruses. An air purifier will help in getting rid of mould spores, pollen and other harmful bacteria floating in the air and your family will notice a significant improvement in overall health.
  7. If allergies are a problem in your household, bringing in an air purifier will get rid of allergens.
  8. You will be doing a favour to your lungs by providing them clean air to breathe. Keep in mind that long-term exposure to pollen, dust, pet dander and other airborne pollutants can lead to many health issues.
  9. A high quality air purifier will help in preventing the spread of germs and other harmful bacteria by neutralising almost all of the airborne bacteria and viruses.
  10. Air purifiers generally do not take up too much space. These are available in a wide variety of sizes and you will definitely find one that fits perfectly in various rooms of your house.

What is HEPA?

HEPA stands for High Efficiency Particulate Air filters. These filters can be made of any material but these are capable of trapping 99.97% of airborne particles that are bigger than 0.3 µm. You can’t see anything with naked eyes that is less than 10 µm in size.

The typical filters in air conditioning units are capable of only capturing particles that are bigger than 10 µm in size whereas HEPA filters are capable of removing even smaller sized particles such as pollen, pet dander, smoke, dust, harmful bacteria and viruses.

Features to Look for in an Air Purifier

When you start researching air purifiers, you will find that there are hundreds of brands with each brand offering multiple models. Therefore, you need to carefully compare several features in order to get the best value for your money when buying any air purifier. Here’s a list of some of the important features you should consider.

HEPA Technology

Make sure the air purifier uses HEPA filters. As described above, HEPA filters are capable of removing 99.97% of particles that are less than 0.3 µm in size. It essentially means that air purifiers with HEPA filters will ensure cleaner air in an enclosed space.

Area Coverage

When it comes to choosing the size of the air purifier, you should first measure the area of the room where you are going to place the purifier. Experts recommend minitower or desktop models for small rooms that are up to 155 square feet in size. For bigger rooms, it is recommended to invest in a console or a tower model that is capable of covering an area of more than 300 square feet.

In addition, you should also pay attention to the air change per hour rate. You can measure this by calculating the volume of the room in cubic metres which would be divided by the air flow rate of the purifier in cubic metres per minute. Ideally, your purifier should give at least 2 air changes each hour in order to be effective at cleaning the air inside a room.


Most of the models available in the market today are compact in size which means you can easily place them in a corner and these will keep working efficiently. Dimensions only matter if you want to move the air purifier from one room to another but generally, people tend to buy separate purifiers for different rooms.

Weight and Portability

Air Purification DeviceWeight of the purifier and its portability only matter if you plan to use the same purifier for different rooms of your home. If you are planning to buy a purifier for a smaller room, you should go for a desk model that can be easily placed at a shelf and is easy to move around.


Noise levels matter with air purifiers as these machines are always running. In other words, you will have to live with the air purifier. So, find the noise rating of the machine and consider the fact that your refrigerator produces noise levels of around 50 dB. The noise rating should be available on the packaging. If noise is a concern, choose a unit with multiple settings. You can run it on high setting where nobody is there in the room and you can then run it on low setting when you are in the room.

Another option is to buy a bigger capacity air purifier which can be continuously run at low setting to allow cleaning of air much more efficiently and much more quietly in a smaller room.


All the models typically look the same but if design is really important for you, you can always find an air purifier that not only works great but also looks great. Pay attention to some of the other features such as timers and programmability. It will allow you to operate the unit in an off-hands manner.

Smartphone App

Internet of things is a reality and these days, you have a lot of devices that connect to Internet. This is also true of air purifiers. Some models available in the market allow you to control various functions with the help of a smartphone app. Buy one with this feature if it is really necessary for you.


Some models of air purifiers are multi-functional. They not only work as an air purifier but also have a fan inside and a heating element which means you can also use them for heating the room. The fan can be used as and when you need it.


Needless to say, you would want to invest in an air purifier that offers multi-year guarantee. You wouldn’t want your air purifier to break down within a few months or within a year. It’s an appliance that should keep working on its own without any issues.
