Keep your environment cleaner and smelling fresh with the Honeywell True HEPA Allergen Remover Air Purifier.

Through the years lots of dust accumulation formed in the vents plus recent construction. I found myself sneezing and dusting  frequently. Once I purchased hepa filter I noticed the difference immediately. My morning and nightly sneezing ceased  and no more weekly dusting!

I noticed a difference in my allergies the first night I used this unit and it worked well for about two weeks, but then became very noisy. The instruction manual suggested changing the filter when the unit became noisy. The filter is supposed to last up to year, so I was puzzled, but ordered a new HEPA filter and pre-filter thinking I may have gotten a defective filter. Same thing happened -- it worked well at first, but after about two weeks the unit became very noisy again.panasonic air purifier f-vxh50h The bedroom is not excessively dusty and I vacuum regularly. bosoung air purifierI can't afford to replace the filters in this unit every few weeks, so I'm going to return it.blueair airpod air purifier Works well, but filter doesn't last

Air purifiers are clean indoor air, but do nothing for indoor humidity levels. They remove dust and smoke from the air, as well as allergenic substances like animal dander and pollen.

Humidifiers add water into the air, but do not clean it. They are used to relieve health issues from dry air and help reduce static electricity in the home. Mechanical air purifiers use filters to remove relatively large airborne pollutants, such as dust and pet dander, from the air. Filters are often made from foam, pleated paper or polyester, or some other synthetic material. A high efficiency particulate air filter, commonly known as HEPA, is capable of removing 99.97 percent of airborne particles. HEPA filters can remove extremely small particles, but cannot remove odors. An air purifier may combine a HEPA filter with a charcoal filter to help reduce odors. Humidifiers add water to indoor air, increasing the relative humidity of the indoor environment. Dry winter air can cause chapped skin and contribute to respiratory problems. Adding moisture to the air with a humidifier can reduce dry skin and decrease breathing problems, including lessening coughs. Adding humidity to indoor air can also reduce static electricity and prevent wooden furniture from cracking.

Four main types of humidifiers are ultrasonic, impeller-driven, evaporative and steam vaporizers. Ultrasonic and impeller humidifiers both produce a cool mist. Ultrasonic models are quiet because they use ultrasonic waves to produce mist, while impeller models use a rotating disk that can produce noise. Evaporative humidifiers use a fan to evaporate water into the air, and are also cold humidifiers. Steam vaporizers create a warm mist by heating water with an electrical element. Some models allow the mist to cool slightly before exiting the machine, and are known as warm mist humidifiers. The standing water in humidifiers can become home to a wide variety of bacteria, mold and fungi. When the humidifier is turned on, these organisms can be released into your home’s air, and breathing them can cause lung problems and even infections. In the past, disinfectants used with humidifiers have also created problems. Minerals from the humidifier’s water tank can be released into the air, where they settle out as a fine white dust.

Humidifiers that use heat to evaporate water are prone to mineral build-up on the heating element, and the filters in evaporative humidifiers can also harbor bacteria and molds. You must keep humidifiers clean, and you need to occasionally descale them to remove mineral build-up.
