Air purifiers work either by filtering out the particles hanging in the air, or by simply neutralizing without filtering. They sanitize the air, removing toxins and pollutants. 

Air purifiers are generally effective, but they won’t be able to remove particles that have already stuck to furniture surfaces.

They can only neutralize and sanitize the particles still freely “floating”, but you’ll need a different cleaning method for particles already in beddings or couches.

Harmful free radicals such as Radon are a silent killer. Natural radioactive elements produce a colorless radon gas that can seep through hard materials such as rocks and granite, affecting your home.

These harmful radicals can also penetrate your house through the cracks on surfaces, especially on floors and plasterwork. Radon can damage your lung’s inner cell linings which can cause cancer.

Fortunately, air purifiers can effectively reduce—even eliminate—this risk as it sanitizes the air. Because of this, people living in vulnerable areas can have a longer and healthier lifespan.

Of course, make sure to immediately repair the cracks that appear on your house for your own security and safety.
