Buying guide, where to buy an air purifier

Buying an air purifier is something that requires your full attention. It is important to take stock of the current market proposals and know how to differentiate between the different air purifier offers before deciding. It is not about investing without knowing a device because a salesperson tells you a series of options with unpronounceable scientific names.

There are hundreds of brands that sell air purifiers. Not all devices will give you the same results or have the same features.

You can consider from the beginning that an effective model will necessarily cost you several hundred pounds.

An air purifier is not a simple fan. It is a combination of complex scientific technologies.

What is the use of the air purifier?

Which purifier to choose? It is important to determine the area of ​​the house or room from which you want to purify the air. These data will allow you to make a first classification through internet proposals or appliance stores.

If you want to purify the air in an office or bedroom with airtight doors, you can look for a small air purifier model. For all other proposals (house, office building, open space, apartment with one or more bedrooms), check the total area of ​​the accommodation to make your choice.

Very small models, which give you a purification of about 20 m2, have low performance and a high-cost price. They are inexpensive but require you to change filters very frequently for a global price that increases over the months.

What air purifier options to choose?

A purifier allows you to clean the air of hundreds of substances that are harmful to health: tobacco smoke, microparticles, pollens. Therefore, choose the filtration system that suits your health needs.

POLLEN, HAIR, AND DUST: The air purifier is ideal for allergic to pollen, animal hair, breathing difficulties, or people with asthma. A pre-filter is often used to purify the air by cleaning it of coarse dust and animal hair. It is, therefore, a HEPA filter that traps pollen and dust from the indoor air. State-of-the-art HEPA filters remove 99.95% of all microscopic allergens and contaminants, down to 0.01 microns.

SMOKE – Do you smoke or cook and are looking for an air purifier to remove these dangerous and smelly substances from your home? Look for a state-of-the-art HEPA filter or charcoal filter.

NANOPARTICLES: Millions of chemicals vitiate our indoor air. They provoke more or less visible reactions depending on the age and sensitivity of the accommodation occupants. These microscopic chemical components have proven toxic effects on living beings: carbon filters, bamboo fibre filters, standard HEPA filters and nanofiber cartridges.

TOXIC GASES: numerous toxic gases pollute our indoor air: carbon monoxide, formaldehyde, nitrogen dioxide. These are filters composed of activated carbon and the wide range of HEPA filters that allow us to trap and destroy the molecules of these dangerous gases.

MICROBES, BACTERIA and VIRUSES: thanks to functions such as photocatalysis, with or without UV or ionization, microbes, bacteria and viruses are trapped or destroyed. This function is ideal for fragile people, babies, the elderly, pregnant women or people who are immunosuppressed.

Buying an air purifier with its accessories

Choosing the best air purifier also means choosing the one that offers the best technological features. Not all models contain the same filters and are not sold with the same accessories.

Some air purifiers will offer remote control for remote start, a control monitor with one or more measurement probes, applications to connect them to other home automation systems.

Low and mid-range air models often don’t offer a numeric reader. Without air analysis and apparent figures on the presence of indoor pollutants, it is impossible to know if the scrubber is effective or not.

How much does an air purifier cost after all?

To buy an air purifier, you need to take into account not only its purchase price but also other criteria:

• The price of the filters, their number and the frequency of their renewal. Changing the filter every three months is expensive and very harmful to the environment. Beware of multi-filter purifiers with outrageous prices.
• The energy consumption of an air purifier is reasonable unless it offers options like heating the air or cooling the room. High-end air purifiers generally provide a “sleep” or “power save” mode for lower consumption.
