Filterless air purifiers are a relatively new invention in the air filter market. These air cleaners have templates inside them, each with an opposite charge, to attract dust and dirt from the air. The charged particles then stick to the plates inside the air purifier. Cleaning is simple; you merely wipe them off or quickly immerse them in slightly soapy water (depending on the model) and swish them around until they become clean again. You then let these plates air dry and reinsert them so they can go back to work, with no disposable filters to replace. In some cases, the purifiers also have ionization pins that should be gently cleaned with a Q-tip and alcohol. Again, they should be allowed to dry so that there is no chance of electric shock or other hazard once they're turned on.
Filtration systems are becoming more necessary with things such as air pollution, dust and dander in our homes become more and more prevalent. With new construction going up every day, homes are becoming ever closer together, and cars on the road increase pollutants in the air as well. Asthma and allergies are also more prevalent these days than in years past. Therefore, air purifiers can help greatly reduce pollutants in the air inside your home, and make it both easier and more pleasant to breathe while reducing congestion or allergy symptoms.
Fairly recently, HEPA air filters were state-of-the-art in the air filter industry. Now, however, filterless systems are becoming more popular. They are cheaper and easier to operate, seldom break down, have no expensive, hard to find disposable filters to replace, and perhaps most importantly, are almost silent in their operation. This is especially important if the air filter is in a location such as your bedroom where you need quiet in order to sleep.
Also relatively recently, these filterless systems were very expensive, even if they were of high quality. Now, however, they have become less costly as competition has brought prices down. This means that a filterless unit is very affordable, and doesn't cost any more than one with a filter does. It also generally lasts quite a bit longer since there are no moving parts to break down.
You can buy purifiers that supposedly filter the air in up to 1000 square feet of space, or smaller room-sized ones that generally cover about 250 square feet. Even though it may seem like a good idea to buy one central filter that covers up to 1000 square feet, it's generally more cost-effective and efficient to buy smaller ones. This is because airflow does not go around corners, through walls, etc., particularly well. Therefore, your air is going to be cleaner and it's going to be filtered more efficiently if you buy smaller units and place them strategically throughout your home. In general, you should buy one unit for about every 250 square feet in your home. For the best results you should place one in each "enclosed" room such as a bedroom, while a large open space such as a combination living room/dining room may only need one unit for the entire space, depending on how large it is.
There has been some concern over the ionization process for some of these filterless air purifiers because of the small amount of ozone they produce, but if this is a concern for you, most of these systems have separate controls so that the ionization process can be turned off. The choice is up to you. Regardless, however, filterless units can save you a lot of money both in energy consumption and filter replacement costs, and may actually be even more efficient than those with filters.
