The air we breathe everyday is filled with numerous impurities. Although a greater part of the air pollutants originate outdoors, they inevitably creep into our homes and offices. Unlike the outdoors, the air inside a room does not circulate as freely and hence gets saturated with dust, chemical fumes, odors and microorganisms.

These substances can cause serious damage to a person’s health such as allergies and breathing disorders. Room air purifiers help prevent such problems. These devices draw in the air, pass it through a filter system and then release the fresh, clean air back into the atmosphere.

Room air purifiers replaced tabletop air cleaning units in the 1990s. The tabletop unit was ineffective because of inadequate volume of air being circulated through it. Room air purifiers are more powerful and can circulate a larger volume of air, thus making breathing safer. The size of the unit depends upon the size of the room. Usually, air-purifying systems are available for rooms of 500 sq ft and above. Most air purifiers are mounted on wheels and can be easily moved from one room to another.

There are different types of room air purification systems available. The HEPA or High Efficiency Particulate Air filter unit is one of the most common home filter systems. This purifier is effective against more particulate matter but ineffective against gases and odors.

Ionic air purifiers release negatively charged ions into the room. These bind with the positively charged impurities, making them settle down. An ionic air purifier may contain a filter to separate out this dust.

The third popular room purifier is the ozone air purifier. This unit releases the reactive oxidant into the air. Ozone can be used to kill bacteria. It also combines with several gases and odors to nullify their effect. However, excess ozone exposure can be harmful so care should be taken when using this product.

With such a wide range on offer, the right choice depends upon the size of the room, the amount of air pollution and finally the budget.

Ionic air purifiers consist of negative ion generators that charge impure particles in the air to settle down on the surfaces of the rooms in which they are set up. However, activity in these rooms may again increase toxic particles in the air. As a result, many of this kind of air cleansers use the technology of electrostatic precipitation which captures the harmful particles on the oppositely charged electronic plates.

Ionic air purifiers come in various sizes and prices. There is the Biozone 500 home purifier. This can be used in areas of about 250sq. ft., the Biozone 3000 which can be used in areas of about 3000sq. ft. This is suitable for areas of high impurity levels such as commercial places, industrial places and large houses. The Biozone 2000 can be used in areas of about 2 000sq. ft. This type is suitable for commercial places and large rooms. All these types do not require skilled maintenance, they have a 3 year warranty and come with a money back guarantee.

Ionic air purifiers are safe to use as they do not release harmful substances into the air. They are not noisy. Their filters need no replacement. The most advanced type is the PHI Cell ionizer that produces numerous negatively charged ions. These ions ensure maximum effect of this kind of air filter.

These filters are of much benefit to people with breathing problems such as asthma and allergies. They are especially beneficial to the vulnerable group of people which includes, pregnant mothers, the elderly, and children. The help maintain health by reducing the chances of the spread of airborne diseases.

UV air purifier uses ultra violet light to deactivate and eliminate harmful micro organisms that are present in the home or office environment. These may be bacteria or viruses. They are built using a technology that will perfectly combine with other purification systems so as to achieve the maximum results and benefits. This technology will effectively eliminate mold and tiny toxins.

UV air purifiers will act by changing the DNA of the harmful microorganisms so that they will not survive. It should be noted that this technology will not affect the DNA of human beings. they are completely safe for use in the homes and so you should not have any doubts while purchasing them.

The UV air purifiers are considered to be very effective in killing of all types of air-borne germs, bacteria, and other microorganisms. This has made them to be popular in hospitals and high profile theaters. They have also been used in prestigious hotels. However, this kind machine can not act as an air filter on its own and is therefore used in combination with other kinds of air cleaning systems so as to ensure for a perfectly cleaned air free of all air pollutants.

There are various types of this kind of machines available in the market. They come in various sizes, shapes, and prices. There are portable ones and those that are not portable. You are sure to get a unit that suits you taste and budget. Investing in this kind of machine is a cost effective venture as you will be able eliminate the expenses incurred when your family members are infected by airborne diseases.
