Overview
The Austin Air Allergy Machine Standard (HM405, B405A1) is designed specifically for individuals with asthma and allergies. It features a 360° filtration system that includes four stages, including a medical-grade HEPA filter and a lightweight HEGA carbon cloth. This allows it to efficiently remove allergens, gases, chemicals, and odors from the air, making it ideal for rooms up to 750 square feet. The machine is easy to use, has three fan speeds, and operates at a relatively quiet noise level (39.8 dB at the lowest setting).
One of the standout features is its low-maintenance design, requiring the pre-filter to be vacuumed monthly rather than replaced frequently, which helps keep operational costs down. The unit's filter is designed to last up to five years, although heavy use might reduce its lifespan to about 2-3 years.
With its solid steel housing, available in several colors like sandstone, and built-in caster wheels, it's portable and durable. The machine comes with a 5-year warranty on both mechanical parts and the filter (pro-rated), giving users confidence in long-term reliability.
Overall, this model is highly regarded for its robust filtration performance and longevity, especially for allergy sufferers.
