HEPA filter technology is used in the most effective home air purifiers in the industry. Blueair this HEPA technology combined with electrostatic technology to clean indoor air. The Blueair 403 is perfect for homes with residents who suffer from allergies or asthma. The air is left safer and cleaner for people to breathe. The use of both filtering systems makes the air purifier stronger and more effective. The Model 403 is also convenient for its size and stylish design. The air cleaner requires little energy to run and is safe to be left on overnight, making it easier for families to breathe the air indoors.

Charlotte Knot from Macon, Georgia is one person who knows the power of Blueair’s 403. Mrs. Knot lives with a full household of three sons, her husband, and her father-in-law. In order to keep the entire household happy and healthy, Mrs. Knot invests a lot of time doing laundry, cleaning and cooking. One of her sons, Brian, suffers from allergies and has trouble sleeping due to a runny nose and sore throat. Her husband is a smoker who smokes his cigarettes in the family living room. With a son so sensitive to allergens and a husband who smokes in the house, Mrs. Knot knew she had an air pollution problem. Brian’s allergies were not only acting up from his father’s tobacco smoke, but he also experienced allergic reactions to certain cleaning products and dust in the house. Mrs. Knot researched how to improve the quality of her indoor air and found out that a home air purifier is the best way to make the indoor air clean.

Mrs. Knot purchased a Blueair Model 403 to help her with her home air pollution problem. The 403 was the best fit for Mrs. Knot’s situation due to its effective hybrid technology and the size of room it was able to handle. The Model 403 is equipped with a HEPA filter designed with large air holes. The larger air holes allow the air to flow through the filter more easily. This creates a strong airflow and it also keeps the air cleaner running very quietly even on the highest speeds. The combination of the HEPA filter with the electrostatic technology inside the air purifier makes it especially effective at removing harmful contaminants from the air. The unit is able to attract particles and give them an electric charge, causing them to stick easier to the HEPA filter.

The 403 by Blueair uses only 50 watts of power to run. Mrs. Knot is able to leave the air cleaner running all night in order to clean out the tobacco smoke and other particles from the air while her family is sleeping. This keeps the air clean through the night and leaves the air fresher smelling and free of any irritants in the morning. Since the unit weighs only 34 pounds, Mrs. Knot finds it easy to move it from one room to the other, wherever it may be needed. When her husband is enjoying a cigarette in the living room, she can easily move the air purifier into that room in order to absorb the smoke. The home air purifier also comes with the option to add a SmokeStop filter. The SmokeStop filter is a filter that adds more activated carbon to the air purifier in order to absorb more smoke from the air. When Mrs. Knot chose to add the SmokeStop filter to her already powerful home air purifier, she was shocked to find that the smoke was no longer present in the room even after her husband had just put out a cigarette. The unpleasant odor of tobacco smoke is no longer in the air, and the particles and allergens that were causing her son to have sleepless nights were also absorbed and eliminated by the Blueair 403. Mrs. Knot has found that the Model 403 is the most effective and best choice of air purifier for her family.
