Today's energy-efficient homes tend to be air tight, staying warm during the winter and cool during the summer. Unfortunately,the house isn't allowed to breathe and open windows are not always a good option. Air purifiers are designed to bring that touch of fresh air indoors.
- Air purifiers will help to avoid developing one of the many medical problems like asthma, emphysema, allergies, cardiovascular diseases, etc.
- Cleaner, better quality air will allow for more energy at work and home activities.
- Air purifiers can help you eliminate pet danders and odor helping you maintain the health of your indoor home.
- Kids and elderly people are more prone to air borne diseases.
Due to advances in science and technology, there are now four methods that are used in air cleaners. Most air purifiers use more than one technology to better clean the air. Most of the machines recommended in our air purifier reviews section, utilize more than one of these.
A specially designed filter effective against many particles. HEPA filters remove smaller allergens like dust, smoke, chemicals, asbestos, pollen, and pet dander.The more times the air passes through the HEPA filter, the cleaner the air becomes. The room capacity of a HEPA air purifier will determine whether the air cleaner can handle your air purifying needs.
Electronically charges particles causing them to attract to collector plates or fall to the floor.
Creates ozone, which seeks out contaminants.
Removes chemicals, fumes, and smoke.
Different brands of air purifiers have different features. Here are some additional features to look for.
- High-Efficiency Particulate Air (HEPA) filters remove 99.97% of air pollutants .3 microns or larger from the air. HEPA filters also remove tobacco smoke, household dust, mold spores, animal dander and pollen.
- Frequency of filtering cycles (average every 10 minutes) can vary between models.
- Check filter control is available on some models.
- Speed controls for times when filtering needs vary.
The most important thing to look for when you buy an air purifier is the correct size for your room. Air purifiers are portable and can be moved from one room to another, provided the rooms are similar in size. Air purifiers can be installed anywhere - in the bedroom, drawing room, dining room, office, restaurant, hospital and so on.
To make the best choice, learn what CADR means. The Clean Air Delivery Rate (CADR) is based on the cubic feet of air a purifier can filter per minute. The higher the CADR number the faster the unit cleans the room's air. Purifiers with the CADR seal remove tobacco smoke particles, animal dander, mold, mildew, dust and pollen particles.
Square footage x .75 = CADR
Example: If your room is 14 feet by 15 feet, which equals 210 square feet, you'll need an air purifier that has a CADR of at least 151 i.e. 210 x .75 = 151.2 If an air purifier isn't available with the exact CADR you calculate, round up. For instance, if your room size requires a CADR of 204, purchase one with a CADR of 220.
If you have a room with ceilings higher than 8 feet, move up to the next level CADR for a larger room. If you have an open floor plan, purchase two small units. The units can be moved to different areas in the room, cleaning the air more efficiently than one unit.
- We take in 24,000 breaths a day
- Our daily food intake *2kgs.Our daily water intake *3.7 kgs
- And our daiy air intake ?A Whopping *13.9 kgs.
- Indoor air is often 10-30 times more polluted than out door air.
Yet we pay so much attention to what we eat and drink ,and so little to what we breathe.
