But, firstly, there are a few factors that must be considered before buying an air purifier.

OGAWA Ultimate Germagic is an innovative air purifier that incorporates germicidal technology. Germagic is an anti-microbial coating that provides “contact-killing”, “release-killing”, and “anti-adhesion” to HEPA filters for the killing of bacteria, viruses, and fungi. It makes the air cleaner, healthier, and purer.

Filtration process

Ogawa Germagic Air Purifier comes with a three-layered filtration process to provide you with clean and pure air up to 99.97%. It includes highly effective HEPA filters, a Deodorization filter, and a protective shield that wraps these filters to enhance the life span of main filters.

  1. Germagic HEPA Filter

A HEPA filter is sandwiched between the protective shield and deodorization filter. It is a standard set by the Department of Energy US for air purifier filters; HEPA stands for “High-Efficiency Particulate Air” filter. These filters are known as the best filters globally due to their nanofabrication, which does not allow tiny particles to pass through. It cleans out almost 99.7% of airborne particles, bacteria, mould, fungi, and viruses and makes the air pleasant for breathing. It can eliminate particles larger than 0.003 microns, so you are safe from many contagious pathogens and allergens.

  • Deodorization Filter

The deodorizing filter eliminates all the foul odour and smell of rotten food from the air using its super-Nano technology. A bad smell can cause disturbance in your mood or headache; this filter makes you feel good and refreshed by adding a pleasant scent to the atmosphere.

  • Protective shield

A proactive film is present on the top of these two filters to provide protection and increase their life span. This layer can trap Marco particles, hairs, and insects before reaching the HEPA filter.

Coverage area and CADR

Air purifiers always have a recommended room size mentioned in their manuals; you should consider the room size you will be using it in before purchasing. Ogawa air purifier can work perfectly in room-sized from 150 sq. ft. to 250 sq. ft. Buy your air purifier considering your room size to achieve optimal performance.

CADR stands for “clean air delivery rate” and means how much air flows through the filter per minute. Ogawa air purifier has a CADR of 210 m3/hour. It determines how fast the air purifier cleans the air from contaminants and bacteria. It is measured in CFM cubic feet per minute, but it is not a reliable number. Let’s assume that there is a gap in the fitting of the filter, which is a design drawback resulting in the air purifier having a definite high CADR. Still, it doesn’t mean that the air purifier is very fast and efficient. On the other hand, a HEPA filter that is somehow blocked by pollutants and needs to be changed will have relatively low CADR, but it can stop more dust, bacteria, and microelements.

The three-way killing of Microbes

  • Contact Killing: In this way of removal, Viruses and bacteria are eliminated upon contact with HEPA Filter.
  • Anti-Adhesion Germagic coating: It prevents sticking and build-up of the microbial carcass to filter. Keep the surface constantly clean, so the filter’s life span is increased.
  • Release Killing involves the active release of Anti-Microbial Agents that seek and destroy harmful microbes suspended in the air.
