The 5 best air purifiers of 2024
Air purifiers remove viruses, dust mites, bacteria, fungi, pollen, pet allergens and other microorganisms. Check out our recommendations here.
According to the World Health Organisation (WHO), indoor air is 10 to 30 times more polluted than outdoor air. For those with allergies, this can mean reduced wellbeing and health. Air purifiers are in high demand due to the growing concern over the quality of air we breathe. Especially when temperatures are lower, it is customary to keep windows closed to protect ourselves from the cold at night. Moreover, often it is also necessary to close the house for other reasons, such as noise, pollution, pollen, light, etc.
With the house completely closed, the dust in the house accumulates, humidity increases and the ideal environment is created for the mold to appear and also for the multiplication of microorganisms capable of causing or worsening allergy or asthma symptoms, known as mites. Know that all houses have mites and mold in small quantities. They are microscopic and are everywhere. You just have to be careful so that they do not multiply out of control.
To help keep mold and mites under control, an air purifier can be an essential piece of equipment, especially for those with allergy symptoms and babies, as their immune system is still developing.
Air purifiers are used to remove impurities from the air, and can do this through filtering or through other processes that sterilize the air, eliminating viruses, bacteria, pollen, mold spores, etc.
Types of air purifiers
Air purifiers with filter
In general, these equipments use HEPA (High Efficiency Particulate Air) filters, and are able to filter 99.9% of particles larger than 0.0003 mm present in the air. It is also common to use activated carbon filters in combination to help reduce odors in the environment, such as smoke and pet odor.
•Pros: they help reduce the dust of each, because all the air circulated is filtered.
•Cons: they can be noisy and can also make the room a little cold, because the air of the environment is ventilated constantly. In addition, it is necessary to clean the equipment filter at least once a week and it is also necessary to replace the filter every one or two years (according to the manufacturer's instructions).
Air purifiers without filter (air sterilisers)
Most purifiers without filters generally have a ceramic heating core that heats the air to temperatures of up to 200ºC, destroying contaminants such as viruses, bacteria, mites, pollen, mold spores, etc. immediately. The heating is located only inside the appliance and does not contribute to the increase in temperature in the environment. They also help reduce odors.
Pros: they are completely silent because the air circulates only by convection (there is no forced ventilation). In addition, as there is no filter, there is no need for cleaning, maintenance or replacement.
Cons: they do not help with dust control.
In addition to the types mentioned above, there are also some devices that use UV (ultraviolet) light and ions (particles with an electrical charge) for air purification and can be combined with a filtration system.
A clean environment is a prerequisite for quality of life and an air purifier will help you a lot. See 5 great options for you to receive a quality product without leaving home.
