Now more than ever, in times of Covid-19, looking for ways to purify the air has become an obsession and we have all kinds of techniques for it.
How to purify the air in your home quickly and easily during Covid?
The SARS-CoV-2 coronavirus is transmitted through respiratory droplets, you will also have heard the word; aerosol sprays. These are generated when talking, coughing or sneezing and if these micro droplets are expelled when the patient is at his highest viral load, you should be protected if your immune system is not strong.
A good interior ventilation reduces the risk of contagion.
Without a doubt the most effective way to purify the air is by opening the windows and doors and letting fresh air in. Without a doubt this is the most effective measure to reduce the risk of contagion.
How to properly air your home?
To air your home properly it is recommended that:
- The ventilation is opposite and diagonal. In other words, it is preferable to open several windows and / or doors, even if it is only a few centimeters than just one completely so that there is air coming in and out.
- Ventilate all rooms daily.
- Open windows for at least 15 minutes when entering a room, especially when other people have used it.
- Unload the toilet with the lid closed, since this discharge of water can generate aerosols that can contain viruses.
- The use of fans is not recommended. There is a false belief that fans renew indoor air and it is not. On the contrary, the fans help to remove and disperse the aerosols that may contain the virus within the room itself or to other nearby rooms.
Other recommendations to reduce Covid infections is to be more silent. In Spain compared to the European average, we are noisy citizens, so by lowering the volume of music or television you speak in a lower voice and this can reduce the emission of aerosols up to 30 times.
Have plants at home to purify the air.
You probably already know the ability of plants to generate oxygen and therefore purify the air. But did you know that some plants are better than others when it comes to purifying the air.
As Arrevol reports; These are the plants that we have within our reach that best purify the air in our home:
- Potus (Epipremnum aureum): It is effective in absorbing formaldehyde, xylene and benzene.
- Spatifilo, peace flower, wind sail, dead flower (Spathiphyllum sp.): Absorbs benzene, xylene, ammonia, trichlorethylene and formaldehyde, which are the five pollutants analyzed in the report by NASA.
- Mother-in-law's tongue, tiger's tongue, sansevierias, sword of St. George (Sansevieria trifasciata): It is good at removing benzene, xylene and toluene, trichlorethylene and formaldehyde.
- Bamboo palm or Chinese palm (Raphis excelsa): It is responsible for eliminating formaldehyde, xylene and ammonia, although we must bear in mind that it can reach 3 meters in height.
- Rubber tree (Ficus robusta): It is effective in the elimination of formaldehydes and helps to balance the humidity of the environment.
Invest in an air purifier
Air purifiers that have microparticle filters. The most popular are those with HEPA certification, which are characterized by their great filtering capacity, trapping up to 99.9% of harmful particles present in the air.
We recommend that you take a look at this list of the best air purifiers that Top Gama has made.
Homede air purifier: a fan and a filter.
Yes, as you hear it; a group of researchers in Spain has shown how to clean the air of aerosols in a standard classroom and avoid contagion for less than € 50.
Although it is 15% less effective than an air purifier that we have already talked about, this option is a great opportunity that allows most people to clean the air at a very low cost and the percentage difference, experts say that is not a problem.
The Laboratory for Research in Fluid Dynamics and Combustion Technologies (LIFTEC), a joint center of the CSIC and the University of Zaragoza, has shown how simple this system is: the filter of the LIFTEC group is attached to the fan with adhesive tape, it is placed in a more or less centered area of the room. It is then that the air that air passes through the filter attached to the fan retains the aerosols.
