My Slevoo Air Purifier Review

What’s in the Box

  • Slevoo Air Purifier
  • 3-in-1 HEPA air filter (installed)
  • User Manual

Review

Slevoo Air Purifier isn’t some fancy air cleaning unit that supports various modes, Wi-Fi and so on. This sleek air cleaner can be described in 3 words: cheap, compact, quiet.

For a little over 40 US dollars you get:

  • Removing particles down to 0.3 micron with 99.97% efficiency. The particles include dust, smoke and other odors, pet dander, hair.
  • The air purifier that is energy efficient.
  • Quiet operation which is a great news if you are planning to use the Slevoo in your bedroom at night.

It is also has a filter indicator that blinks red when the air filter requires a replacement.

Suitable Room Size for Slevoo Air Purifier

Slevoo for some reason didn’t mention CADR rating in their spec sheet, but I can figure out it by myself using this Clean Air Delivery Rate calculator. Knowing the number of air changes per hour (6) in a specified room (107 sq. ft.) I can measure Slevoo CADR and the result is 86 CFM (cubic feet per minute of air moved).

Is it a good CADR rating? For the price – extremely great!

Now let’s see how the air purifier performs in spaces of different size:

Room size How long it takes to clean room ACH
107 sq. ft. 10 minutes 6
160 sq. ft. 15 minutes 4
215 sq. ft. 20 minutes 3
320 sq. ft. 30 minutes 2

What this table tells us is that the Slevoo air purifier is great for people with allergies who are planning to run it in their ~100 sq. ft. bedrooms or bathrooms. For everyone else, the effective space coverage increases up to 200 square feet before the air cleaner becomes useless.

Or, you can get two of them and place it in 2 places in one 300 – 400 sq. ft. room, diametrically opposed to each other.

Maintenance Costs

Replacement Filters: ~$25 every 3-6 months for BS-03 3-in-1 HEPA air filter (check availability). The filter is identical to the one used in Partu HEPA air purifier.

Electricity Costs: ~$1 per month running 12 hours per day on maximum speed. Use our Energy Consumption Calculator to estimate electricity usage and costs of the Slevoo air purifier based on your local electricity rates.

Total Yearly Costs:~$110 when replace the air filter every 3 months or ~$55 if replace it every 6 months.

Pros & Cons

The Good
  • Very cheap
  • Child Lock
  • Available in 2 colors
The Bad
  • Unknown brand

FAQs

How often should I change the Slevoo air filter?

At least once in 6 months. It all depends on the indoor air quality; the filter indicator will let you know when to replace air filter with a new one.

Where do I put the air purifier?

Preferably near the source of odor.

Wrapping Up

All in all, the Slevoo air purifier is a 2022 newcomer, that hasn’t lost to its more famous counterparts and will continue to rise in the future if the company continues to support it.

It’s probably the major negative thing I can say for now about the Slevoo air cleaner: this brand is unknown and who knows whether it’s going to be successful or not, as only time will tell.

If everything goes in the right direction, the Slevoo is one of the candidates for the best air purifier for 100 square feet bedrooms and bathrooms.
