BlueAir air purifiers are among the higher-end air purifiers on the market today. They are also some of the most aesthetically pleasing and elegant models created to date. They are a step up from the Honeywell and Levoit Air purifiers but still don't meet the level of Filter Queen air purifiers. The most popular BlueAir air purifiers are the classic 210, 215, 203 Slim, 270e slim, 203, and 303 series machines. Most of the new Blueair purifiers come with wifi and Bluetooth pairing for seamless air purification. They have sizes for any size room you need. These Air purifiers are perfect for respiratory issues and people who need a little higher standard of air compared to normal people. Breathe Naturally MERV 17 HEPA filters stop harmful airborne particles down to 0.03 microns small at a 99.97% efficiency level. Capture mold spores, dust, dander, pollen, bacteria, virus carriers, and tons more airborne particles, leaving the air you breathe clean and healthy. Our filters are perfect for those with seasonal allergies, sensitive respiratory systems, and people who just want to Breathe Naturally. Breathe Naturally carbon filters are made from Bamboo carbon and are proudly made here in the USA, supporting American companies and jobs. We take pride in our specially designed carbon filters that are made to be thicker, last longer, and capture more odors and particles that ultimately lead to a longer lifespan on your HEPA filters saving you money and leading to less waste. We recommend changing HEPA filters based on use, usually every 4-6 months for normal use, and every 1-2 months per carbon filter, again with normal use. Those who put extra strain on the air in their homes, such as larger families, people with pets, and people who live in larger cities may want to change their filters more often. Most modern air purifiers come with a filter change indicator light that will let you know pretty accurately when you're due for a change. When changing your filters, dispose of dirty filters in the garbage. Reset filter indicator lights, and enable child lock if needed and available. Breathe Naturally firmly stands behind their filters and trusts them in their homes and the homes of their loved ones. We offer a 30-day money-back guarantee on all purchases. Satisfaction guaranteed or your money back. Our carbon filters are proudly made in the USA. All filters ship from Minnesota, a family-owned and operated company. Do not place the air purifier too close to your head, and refrain from having the air blow directly towards you.
