Cartridge comes with Unit
How it works:
1) Air gets collected at foot level where bacteria and viruses tend to congregate.
2) The air then gets run through the cartridge chamber with High Intensity UltraViolet light, which penetrates thin-walled germs like viruses and bacteria and fatally altering their genetic structure.
3) Your air comes out of the top at breathing level!

Patented chamber forces air around three high intensity UV-C tubes, giving the proper 254 nm dosage to deactivate bacteria and mold. Shielded lights produce no ozone, so the system works continuously in occupied rooms.

No replacement filters to buy or change, simply plug in and run. Powerful fans draw contaminated air in from the bottom and release sanitized air from the top.

Fifteen fan speeds let you balance airflow and noise for sleep time. Cleans the air up to six times per hour in an average bedroom, and the unit is easy to move at 18 pounds.
Pick the right purifier by matching coverage, technology, and daily use to your home and family needs.
- Match the Room Size: Measure the room and choose a unit rated to clean that square footage, or one that lists cycles per hour for similar rooms.
- Know the Technology: UV-C systems deactivate microbes without filters, while HEPA systems capture particles; consider allergies, odors, and maintenance preferences.
- Consider Noise Levels: Look for multiple fan speeds so you can run stronger filtration during the day and quieter modes at night.
- Safety Around Kids: Choose enclosed UV systems with no ozone production and follow manufacturer placement and operating instructions.
- Placement and Care: Place the unit where air can circulate freely, keep vents clear, and follow recommended cleaning for long term performance.
Is this safe to run around babies and pregnant people?
Yes. The UV lights are fully shielded and the unit produces no ozone, allowing safe continuous use in occupied rooms.
Does the RxAir 400 need replacement filters?
No. The RxAir 400 uses a filterless UV-C kill chamber, so you do not need to buy or change filters.
How loud is the unit and can I use it in a bedroom at night?
It has fifteen fan speeds so you can choose quieter settings for nighttime use while still maintaining continuous air treatment.
What certifications or test results support the claims?
The unit is FDA cleared as a Class II medical device and has been proven safe and effective in FDA certified lab testing.
What are your shipping and return policies?
We ship from a US warehouse, offer free US shipping on orders over $100, and accept returns within 30 days, with human customer support available.
