According to Allergy UK, a whopping 44% of British adults now suffer from at least one allergy.
You may be allergic to indoor air pollutants such as tobacco smoke, dust particles, volatile organic compounds, pet dander or mould. Maybe you are looking for an air purifier that can help reduce your symptoms by cleaning the air inside your house.
There are so many models on the market right now, at first it may seem quite overwhelming figuring out how to find the right air purifier for your needs. Hopefully, after reading this short article, you will be well equipped with the knowledge to select the best air purifying solution for you.
So how do you know what air purifier to choose and what to consider when buying one?
Step 1. Find out what you are allergic to
Well, first of all, think about why you need an air purifier in the first place. What are you allergic to? Knowing the answer to this simple question will make selecting the right machine for you much more straightforward.
For instance, one unit may be great at removing pet dander and dust mites from a room, but not so good at removing bad smells and odours. Most machines tend to fall into five common types depending on the technology used for combating indoor air pollution. We are listing them below and if you want to learn more about each of the technology, check out the article "Do air purifiers work?" in which we dive deeper in each air purification technology commonly used in air purifiers.
HEPA-type, True-HEPA and activated carbon air filtration
Photocatalytic oxidation air sterilization (PCO)
UV-C air sterilisation
Ioniser air purification
Ozone generating air purification*
Best air purifiers use a combination of multiple types of air filtration technologies.
* We strictly do not recommend investing in an air purifier that uses ozone generation for indoor air cleaning. According to the California air resources board, these devices purposely emit large amounts of ozone that can pose a severe health risk to humans by harming the cells in the lungs and respiratory airways.
Step 2. Check and calculate your room size
You may be asking yourself, how do I calculate the size of the room to help me pick the right air purifier?
A lot of people who invest in an air purifier end up choosing a machine that is too small for their living or working space. You need to make sure that it is powerful enough to efficiently clean the air and ultimately make a real difference in the quality of your life.
To start, calculate the volume in which you are going to use the air purifier by multiplying the length, width and the height of your room.
To find out how many air changes in your room an air purifier will do in an hour simply find the airflow figure of the unit you are interested in, enter the dimensions of your room, and the handy calculator tool below will show you exactly how many air changes per hour you will enjoy.
To conclude, make sure the air purifier that you are investing your hard-earned cash in can handle the room size you need and you'll be good to go.
Step 3. Decide on the maintenance cost of an air purifier
Enjoying the pollutant-free air in your living or working space will involve individual costs, for example, the cost of electricity or replacement of filters or built-in modules such as UV-C and PCO units.
On average, HEPA filters need replacing every 12 months depending on the air purifier and the amount of particulate matter in the air.
The replacement carbon filters which capture odour molecules and chemical fumes in the air are not reusable and should be changed approximately every three months to a year.
Pre-filters capture larger particles such as dust, skin cells, bacteria, pollen, dander, mould and fungi. These filters are reusable and can be washed with water. We recommend you check the pre-filter regularly and clean it as often as necessary, depending on the levels of pollution, every two weeks to a month is good enough.
When it comes to electricity costs, most modern air purifiers on the market put energy efficiency as one of their highest priorities since these machines run for long periods.
Take a look at the range of designer air ionisers from the Swedish manufacturer LightAir. The compact CellFlow Mini 100, for example, is a very energy-efficient air purifier that is suitable for smaller rooms of up to 20 square meters. It consumes only 1.5 – 3 watts of power!
The IonFlow Evolution series with a beautiful slightly conical stand and a filter-free design consumes only 5 watts of power, very impressive if you are mindful of your energy usage.
Step 4. Decide on the features you need.
Once you have gotten the hardest part out of the way, you may want to think about any additional features that you want your air purifier to have. These can be air quality indicators in the form of an LED light that gives you real-time updates on the quality of indoor air.
The Meaco Clean CA-HEPA 76x5 WiFi enabled air purifier has a built-in particle sensor which analyses the air in the room and automatically varies the speed of the fan. The colour change feature works together with the sensor and the LED light. It either changes to red if the air is dirty or light blue when the air in the room is clean.
Some other standard features that air purifiers may have are:
Night mode allows you to have a good nights sleep with an air purifier working quietly in the background.
Multiple fan speedscontrol the airflow in the room.
Filter change reminderslet you know precisely when a filter needs replacing.
Remote controlallows you to operate your machine remotely.
Wi-Fi connectivity allows you to control an air purifier via an app on your phone or tablet.
So before heading to the checkout page, choose an air purifier that addresses your needs, that is fit for your living or working space and is easy to use and maintain.
