Filtration Technology
The Airthereal B50 uses ozone generation rather than physical filtration, producing adjustable ozone output between 10-50 mg/h to oxidize and neutralize odor-causing molecules. Unlike HEPA or carbon filter purifiers, it doesn't trap particles , instead, it chemically breaks down odors from pets, cooking, smoking, and bathroom activities.
It's EPA Certified for safe residential use, but it's important to understand this is a fundamentally different approach from filter-based purifiers and won't remove airborne particulates.
Noise & Performance
The B50 covers spaces up to 323 sq ft, making it suitable for bathrooms, small bedrooms, closets, and single rooms. Customer feedback confirms it works surprisingly well for its size at eliminating odors in enclosed spaces.
However, noise is a noted concern among users , for a device this small, the audible output may be more noticeable than expected, particularly in quiet environments like bedrooms at night.
Smart Features & Controls
Controls are entirely manual with a simple dial to adjust ozone output from 10 to 50 mg/h. There's no auto mode, no air quality sensor, no WiFi connectivity, and no app control , you plug it in, set your desired output level, and it runs continuously.
While this simplicity means there's virtually nothing to learn or configure, users who want scheduled operation or remote control will need to pair it with a basic outlet timer.
Filter Maintenance
One of the B50's strongest advantages is zero filter maintenance , as an ozone generator, there are no filters to replace, wash, or monitor. This eliminates all ongoing consumable costs that traditional HEPA and carbon filter purifiers require.
Occasional wiping of the unit's exterior is all that's needed to keep it running, making it one of the most maintenance-free air treatment options available.
Who Is This Air Purifier For?
Ideal For
- ✓ Pet owners dealing with persistent odors in small rooms , ozone breaks down odor molecules from pets at the source
- ✓ Renters or apartment dwellers who need odor control in bathrooms, closets, or laundry areas without bulky equipment
- ✓ practical buyers who want zero ongoing filter additions for odor management
- ✓ Anyone tackling cooking or smoking odors in enclosed spaces up to 320 sq ft
Not Ideal For
- ✕ Allergy or asthma sufferers who need HEPA-grade particle filtration , this unit has no physical filter for dust, pollen, or dander
- ✕ Users wanting smart home integration or app-controlled scheduling , the B50 is manual-only with no WiFi
- ✕ Light sleepers needing a silent bedroom purifier , customer feedback flags noise as a concern
Setup is as simple as it gets: plug the B50 into any standard outlet, adjust the ozone dial to your preferred output level, and it begins working immediately. No filter installation, no app pairing, no assembly required.
Start at the lowest ozone setting (10 mg/h) and increase gradually , a faint clean smell is normal, but a strong chemical odor means the output is too high for your space
Position in the area where odors are strongest for best results, such as near a litter box or trash area
Airthereal typically offers a 1-year warranty on their products, but buyers should verify current warranty terms directly with the manufacturer or check the product listing at the time of purchase for the most up-to-date coverage details.
FAQ
Is the Airthereal B50 safe to use around pets?
The B50 is EPA Certified for residential use, but ozone generators should be used with caution around pets, especially birds and small animals that are more sensitive to ozone. At the lowest 10 mg/h setting it produces minimal ozone, but it's best used in rooms where pets don't spend extended time, or run it when the room is unoccupied to clear odors from pets.
Does the Airthereal B50 remove dust and allergens from the air?
No , the B50 is an ozone generator designed specifically for odor elimination, not particle removal. It does not have a HEPA filter or any physical filtration media, so it won't capture dust, pollen, pet dander, or other airborne allergens.
If you need particle filtration for allergies, you'll want a traditional HEPA air purifier instead.
How well does the B50 work for smoking and cooking odors?
Customers report the B50 is effective at neutralizing odors from smoking, cooking, and bathroom activities in small enclosed rooms. Ozone works by chemically breaking down odor molecules rather than just masking them.
For best results with strong cooking or smoking odors, use a higher ozone output setting (30-50 mg/h) and allow time for the ozone to circulate through the space.
How loud is the Airthereal B50 ozone generator?
Noise is one of the most commonly mentioned concerns in customer feedback. While Airthereal doesn't publish a specific decibel rating, users note the sound is more noticeable than expected for such a small device.
It may not be ideal as a bedroom unit for light sleepers, though noise tolerance varies , some customers use it overnight without issue.
Do I need to buy replacement filters for the B50?
No. The B50 is an ozone generator with no physical filters, so there are zero replacement additions.
This is one of its key advantages over traditional air purifiers, which typically require filter replacements every 6-12 months. The unit just needs occasional exterior cleaning to stay in good condition.
What size room can the Airthereal B50 cover?
The B50 is rated for spaces up to 323 sq ft, which makes it well-suited for bathrooms, closets, small bedrooms, and single rooms. For larger spaces, you'd need multiple units or a larger ozone generator.
The adjustable output dial (10-50 mg/h) lets you scale the ozone level to match your actual room size.
