AI summary — not a quote
The Levoit Vital 200S is highly recommended by Reddit users as a quiet and effective air purifier, particularly for bedrooms and pet owners. It is praised for its simple, ionizer-free design and its ability to handle pet hair, though it is noted to be less effective for heavy VOC removal compared to specialized units. While the app and build quality receive positive marks, a significant point of contention is the 'Auto' mode, which some users find unreliable.
Pros
- Quiet operation, especially when used in a room smaller than its maximum rating
- Effective at capturing pet hair and managing allergies
- No ionizer by default, which is preferred by many users for safety and simplicity
- Strong app integration and smart features, though they are not required for use
Cons
- Auto mode is reported by some users to be ineffective or non-functional
- Limited carbon filtration compared to units specifically designed for VOCs
- May struggle to provide adequate air changes in large, open-concept living spaces

AI summary — not a quote
The Corsi-Rosenthal box is a highly effective, DIY air purifier made from a box fan and MERV 13 or 14 furnace filters. It is widely praised on Reddit for providing a Clean Air Delivery Rate (CADR) that rivals or exceeds expensive commercial units at a fraction of the cost. While it is a favorite for budget-conscious users and those dealing with smoke or heavy dust, it is frequently criticized for its industrial appearance and high noise levels when using standard box fans.
Pros
- High Clean Air Delivery Rate (CADR) for large particulates and smoke
- Significantly more affordable than high-end commercial HEPA purifiers
- Highly effective for visible dust capture
- Customizable designs, including quieter versions using PC fans
Cons
- Large, bulky footprint that takes up significant floor space
- Standard box fan versions are often too loud for quiet environments
- Homemade aesthetic may not suit living areas or shared spaces

I learned of a Corsi Rosenthal box (using MERV 14 filters) and decided to build one, but in my haste, I flipped the fan to be blowing air into the center of the box instead of upwards and let it run all night. My best guess is that the incorrectly built Corsi Rosenthal box ended up agitating the particles in our room and we inhaled some while sleeping.
Another good choice is building a CR box. The high setting will definitely be too loud, but this site found a decibel reading of 49 on the low setting
Levoit Vital 200s or Corsi Rosenthal Box
you get an Air purifier called a CR Box/Corsi Rosenthal Box...that does a whopping 440 CFM of air cleaning power. Better than any sub 400 dollar purifier, and better than some 1,000 dollar purifiers...for 90 bucks.
a CR Box/Corsi Rosenthal Box a great way to get cheap particulate coverage. (A CR Box only 90 bucks..and 440CFM power...so will be like 4x more powerful than that Coway...for same price.
