Pure Enrichment PureZone Mini Filters

The Pure Enrichment PureZone comes with 2 stage filtration system. 

  • True HEPA Filter
  • Activated Carbon Filter

True HEPA Filter: The Pure Enrichment PureZone Mini has a True HEPA filter that can clean the 99.97% of air pollutants and remove the dust, pollen, pet dander, and as small as 0.3-micron size particles.

Activated Carbon Filters: The activated carbon filter can clean the VOCs, paints odors, bed smells, smog, and harmful gases.

Pure Enrichment PureZone Mini Coverage

Pure Enrichment PureZone Mini is only intended for personal use, but the company confirmed it could be used in any room up to 54 square feet in size. I recommend you use it in very small spaces.

PureZone Mini has a CADR of about 5-10 CFM in general.

Pure Enrichment PureZone Mini Sound

One advantage of personal air purifiers is that they are extremely quiet. If you run it at low speed, and sometimes even high speed, you won’t notice its sound level. I measure the PureZone Mini’s noise level to be 15 to 30 decibels (DB), depending on its current fan power.

It’s perfect if you need to use an air purifier in an office, as it won’t distract your colleagues.

Pure Enrichment PureZone Mini Power Consumption

Power consumption is an important criterion to evaluate how much energy this purifier will use.

A single charge of the PureZone Mini can last up to 10 hours, and it has a power of 8 watts. Keep in mind that the PureZone Mini uses a rechargeable lithium-ion battery, so it will eventually die.

In spite of this, its energy consumption is extremely low, so you shouldn’t worry about running this air purifier.

CALODY Portable Air Purifier 

Calody air purifier is the same size as water bottles, with dimensions of 2.7 x 2.7 x 6.7 inches. Purify your personal spaces, such as your car, bedroom, and office. Its unique AIR Technology provides a strong airflow that can cover up to 100 ft2/10m2 and cleans the air in 10 minutes. 

 

 

As you know, these air purifiers cover very small areas, so why recommend you use these air purifiers in just cars. The Calody just consumes 2.5 to 4 watts of energy. And if you use this air purifier at a low fan speed, it will produce just 12 decibels, but at the highest fan speed setting, it will produce 30 decibels sound. That’s why this air purifier is a bit noisy.

Filters of Calody Air Purifier

Calody air purifier comes with a three-stage filtration system, including with initial grade filter screen, an Activated Carbon filter screen, and HEPA coating filter.

The 3-Plies Filter is durable and reliable. This can last up to 4-6 months 500 hours and has enhanced abrasion resistance. Safety is our top priority; the product is certified by EPA, CARB, FCC, and UL.

HEPA Filter: The HEPA filter of the Cody air purifier capture the dust particles, pollen, allergens, and as small as 0.3 microns, dust particles.
