The debate about whether you should or shouldn’t use an air purifier is still on and there are plenty of medical studies that give interesting results.
Are air purifiers efficient?
It seems that people fighting allergies, asthma or other respiratory illnesses who used portable air cleaners with HEPA filters did present fewer symptoms in time. They did experienced wheezing and coughing a lot less often, but they still had to take medication, just as much as people who didn’t use the cleaners.
So it appears that purifiers work better for removing smaller particles like smoke, as they are quite lightweight. When it comes to larger particles (dust or pollen), that are going to stay in the air longer, aren’t going to be collected very easy. As a matter of fact, there are cases when purifiers actually made the air dirtier by stirring up dust that was already settled.
Many studies tried and failed to show that particulate matter is minimized, much less to give a health benefit in the real world.
The tests are made in the lab, whereas in the real world, there’s a poor mixing of air. Therefore, particulate matter (PM) in a room is never going to be pulled into the air cleaner. Furthermore, even if the cleaner pulls in all PM in the air now, if you’re not managing the sources of PM, the PM levels are going to rise almost instantly up to where they were before.
You may very well control the sources of any pollutants by always keeping your home clean and well ventilated. Wipe and vacuum surfaces as most of the allergens are found all around you and not that much in the air, anyway.
Are vacuum cleaners efficient for purifying the air?
No vacuum cleaner is efficient unless it has a good filter. Knowing the type of its filter is important when selecting a vacuum cleaner.
The ULPA (Ultra Low Penetration air filter) is the highest-quality filter that you may find at the moment and it’s used mostly for industrial-grade machines in various places: hospital, museums, and industrial cleanrooms. It has an efficiency rate of 99.999%.
The HEPA (High Efficiency particulate air) filters are able to block particles with a 99.97% efficiency, which is quite impressive too. A vacuum like this doesn’t come cheap, and you should pay the extra buck. After all, it’s for your own good.
If you don’t want to empty your wallet, you could also try a vacuum with micron filter that has a similar build as HEPA filters, but don’t have the same quality as HEPA filters.
