Specifications

Austin Air Healthmate Junior Air Purifier - HEPA Air Cleaner - Sandstone How does it work? The key to the Air Allergy Junior consists of two integrated filters that effectively screen out dust particles, pet dander, pollen, and other allergens as air moves through the machine. An advanced backward curved blower draws air through a durable 360 degree perforated steel air intake, and is channeled to the dual filters, which capture 99.97% of all particles larger than 0.3 microns. When the air moves through the carbon cloth filter, it eliminates unwanted odors caused by animals, cooking, smoke, and chemicals. The unique weave of the carbon cloth filter reduces dust while increasing the surface area, helping the filter perform more efficiently, weigh less, and last longer. The Austin Air Allergy Junior does not produce ozone, ions, or negative ions that can be dangerous to those with respiratory problems like asthma and emphysema. Inspired by State-of-the-Art British Military Technology In recent years secrecy restrictions were lifted on a new activated carbon material developed by the British military. This material was a lightweight carbon, weaved into a cloth designed to protect British troops from the toxic weapons of chemical warfare. Researchers at the Austin laboratories developed a method for combining the carbon cloths gas trapping capabilities, with the proven particle filtration of the HEPA filter. The result is the highly efficient HEGA filter.
Customer Review: Not worth the money
I have owned a healthmate junior air purifier for a number of years now. Frankly I can say that it was not worth the money. I bought the filter due to the “warranty” on the main filter. What a joke! After getting a new filter 6 months ago the air coming out smells terrible. When I spoke to Austin Air they informed me that they would sell me a new filter for 50% off. Are you kidding me? I just replaced it and they are asking me to spend even more money with them??
Bottom line, there are MANY other higher rated air cleaners out there that cost much less money and that are more reliable. Do yourself a favor and stay away from this one.
Customer Review: Austin Air=Antiquated Air Filtration Technology
Austin Air Healthmate Jr is missing UV LIght to kill bacteria filtered from the air, ozone to kill airborne viruses and negative ion output. All it has is a medical grade HEPA filter. The filter will need to be replaced before the 5 years it is supposed to last and it will SMELL when the filter gets clogged. I did the research AFTER I bought a Healthmate Jr unfortunately. Also when you buy this bulky item, ask them about a restocking fee and return shipping. Buying and returning one could easily leave you $50-60 dollars poorer. There are better, more advanced, cheaper air filters out there. I now have 2 Multi-Tech 2 XJ3000D air filters and I love them!!

Customer Review: great cleaner volume, loud white noice
Honeywell 50250N 99.97% Pure HEPA Round Air Purifier
This is a review for the 50300 which is similar to the 50250.
This air cleaner really puts out the volume of clean air on high speed, but it is loud. You can not talk or hear over it.
The slow speed is you can hear talking and TV over. Then turn it on high at night for white noice or when you leave the room.
