Environmental studies have revealed that the air inside homes is dirtier than the air outside. People living in congested homes or localities usually live in dirty air.

The best way to deal with this problem is to purchase a good air purifier. An air purifier is a device that cleans the air. It assists in air purification by freeing the air from pollutants and contaminants.

Air purifiers are very beneficial for people suffering from allergies due to air pollutants, and asthma. The allergy inducing particles may come as dust or pollen, pet dander or mold spores.

A home air purifier removes these particles. It also provides protection against hazardous smoke particles and airborne gases that may intrude into the house and bedrooms. It offers a great protection against second hand smoke. Air purifiers convert the dirty and contaminated air into clean air and offer a morning fresh aroma to the whole house.

Different air purifiers use different air purification techniques including mechanical filters, adsorbents like charcoal, and electrostatic charges or ionizers. The additional setups include germicidal UV light and the emission of ions into the air to react with contaminants, making them harmless enough to breathe.

Benefits of air purifiers for asthmatics:

Air purifiers alleviate asthma, and the best air purifier can totally remove the causes by providing high quality air purification. It improves the living of asthma sufferers by air filtration, reducing the dust floating in the air, filtering second hand smoke, and purifying the air of chemical pollutants, car exhaust fumes or other contaminants.

Controversy:

The critics of air purifiers opine that the air purifiers dont offer any significant help to asthma sufferers. They feel that the media has over hyped the devices, and that they cant completely purify the air. Air purifiers cant provide complete protection against secondhand smoke, and cannot completely remove carbon monoxide.

The ionizing air purifiers are particularly under fire. They have kicked up a row that all ionizing models produce ozone (O3 poisonous allotrope of oxygen) that can worsen asthma and decrease lung function. Recent studies are supporting the fact.
