Healthcare providers across the globe agree that the indoor air is unhealthier than the outdoor air. This is because the dust, pet dander, pollen and mold which infest homes and offices are sealed in due to the environment being insulated against heat and cold. This insulation prevents the pollutants form escaping outdoors and thus, they continue to pollute the environment inside, increasing health risks for occupants. These health risks include respiratory allergies such as runny nose, breathing problems and also skin allergies such as itchy skin and rash on the body. You may want to invest in an air purifier if you are a smoker or living with one, if you have mold in your home or if you have pets which you keep indoors mostly. Mold will increase the humidity in your environment, causing breathing disorders.

All the Best office air purifiers will not get rid of all the indoor air pollutants. Some of them will eliminate only particulate matter like smoke from cigarettes, dust and pet dander while others will be better at removing mold and bacteria. You should verify what kind of action an air purifier performs so that you can buy one which fulfills your purpose. 

Most air purifiers are designed for use in a single room. The efficiency of their action depends on air flow and this can only be possible in a single walled unit. If you need it to work for more than one room, you will need to attach it to your air conditioning unit so that the purifying effect can be transferred to the other rooms via the air conditioning ducts. Otherwise, it is better to get separate units for separate rooms. The air purifiers have a CADR or Clean Air Delivery Rate rating. This indicates the efficiency of their service. This CADR rating should be two thirds of the size of the room for effective action.

The working of the air purifier depends on the cleanliness status of its filter. The cleaner its filter, the more efficient is the Air purifier for health. The frequency with which the filter needs to be changed depends on the size of the room and also that of the air purifier. The filters need to be cleaned regularly and changed periodically to keep the air purifier in prime working condition.

Air purifier manufactures claim that their products can eliminate the smallest air pollutants. The size of this particulate matter is determined in microns. The smaller the size of the dust particles in microns which can be removed, the more efficient the air purifier is considered to be.
When it comes to spending on a good air purifier, you should remember that the quality of a product is not always measured by its price. Even if you decide to buy a high end product, you should ensure that you get the warranty for it. Your budget for an air purifier should include the expected cost of filter replacement and also the electricity which the device is likely to consume.

Air purifiers may emit a small amount of ozone gas which should be within the permissible limits.
