Removing mold from your house often involves a lot of scrubbing, cleaning, and sometimes replacing entire walls and floors, but there are ways to prevent mold from developing in the house in the first place. One of the easiest ways to prevent mold growth in the home is to make sure the majority of the mold spores in the area are collected and done away with.
HEPA filters are built into vacuum cleaners and air purification systems to remove as much particle debris as possible and it is effective up to about 99.7% of removing almost anything from the air you could want removed. Smoke particles, pet dander, hair, pollen, dust mites, mold spores, and etcetera are all removed from the air that you breathe and this not only stops mold spores from being able to grow in your home, but also from forming an infection in your body. You should note that not all particles in the air are removed, but since only about 0.3% remain, this last bit that remains is negligible in comparison.
Air purification systems are becoming popular in families that have a history of breathing problems such as asthma and allergies. Since people are spending more and more time indoors these days, especially in work environments, the air that we breathe indoors is becoming much more important. The indoor environments that we work in typically allow the air to become stale. Fans do not really solve this problem very well, since all they do is cause the dust and other debris to be stirred up into the air instead of removed. When purchasing an air purification system for your home, you should make sure that you buy one that can handle the square footage of your home so it does the best job it can.
Vacuum cleaners should also have HEPA filters in them, since their purpose is to pull soil and particle debris out of your carpet. If it does not have a filter on it, then all of the dust and particles that the vacuum collected will be spilled back into the air that you breathe and you might as well not have vacuumed at all.
Remember when you vacuum a carpet, you should vacuum all of it and not just part of it. When you get your HEPA filtered vacuum cleaner, go over the carpet at least twice to get it as clean as you can. If members of your family have allergies, it is probably a good idea to do away with as much of the carpet in your home as possible, since pollen, dust mites, mold spores, and the like will have less places to live if you do.
