How can an Air Purifier help me in controlling my allergies?

Using an air purifier is one of the most effective ways to reduce exposure to airborne dust and allergens. An InovaAir Air Purifier will allow you to breathe air free of dust, allergens and pollutants. InovaAir air purifiers are portable allowing them to be used in the bedroom at night and in your living area during the day.

If you are considering buying an Air Purifier make sure it has a Medical-Grade HEPA Filter (High Efficiency Particle Arrestance).

Most people purchase air purifiers to remove dust and allergens from the air and want the highest level of efficiency available. Medical-grade HEPA filters offer the highest level of efficiency: a minimum capture of 99.97% of particles at 0.3 microns in size and larger. With 1 micron measuring just 1/10,000 of a centimetre HEPA filters will remove dust mites, mould spores, pet allergens, pollens and ultra fine particles from the air.

Medical-grade HEPA filers are made from a very fine paper (not polypropylene or synthetic materials) which traps microscopic particles so fine they will even remove bacteria and viruses. This is why HEPA filters are used in hospital and medical applications, including operating theatres.

With the rise in popularity of HEPA vacuum cleaners and air purifiers, many manufacturers are claiming to use HEPA filters, however the majority of these are not Medical-grade and when tested, fail to filter 99.97% @ 0.3 microns of particles from the air. If you suffer from allergies or asthma it is critical to use an air purifier with a medical-grade HEPA filter.

See below for further information on how to tell if an Air Purifier has a Medical-grade HEPA filter.

Flexible area coverage

The InovaAir E20 air purifier is flexible in operation and can be used in either single or multiple rooms or the entire home or office.

H13 HEPA high efficiency filtration

The filter in the InovaAir E20 system is manufactured using H13 medical- grade HEPA filtration with an incredible 6.4m2 surface area, combined with Technostat® pre-filtration microporous filter technology these filters exceed HEPA filtration standards. Normally only found in commercial environments such as hospitals and cleanrooms. These E20 filters provide the highest level of filtration available.

Green Choice Filters

Large filters not only result in superior filtration and airflow, they also result in:

  • lower energy consumption
  • longer filter life
  • Lower cost over time

HEPA filters known as High-Efficiency Particulate Arrestance filters were originally developed to filter fine radioactive particles. A HEPA filter will filter with a minimum efficiency 99.97% of particles 0.3 microns and 95% of particles 0.1 microns. With 1 micron measuring just 1/10,000 of a centrimetre and the smallest particle visible to the naked eye being 40 microns. 0.3 microns is many times smaller than dust mites, mould spores, pet allergens and pollens. HEPA filters are widely used in medical applications including: cleanrooms, pharmaceutical manufacturing and any environment where clean or sterile conditions are required.Hepa Filter Diagram

Medical grade HEPA filters are made from highly efficient filter paper. The paper is folded in a concertina configuration to maximise the surface area of the filter and allow air to flow through with minimal resistance. There is a certain ratio of filter paper to airflow volume which must be followed in the construction of the filter to achieve the 99.97% efficiency rating. If there is not enough filter paper, efficiency will not be to HEPA standards.

How are HEPA filters made?

The filter paper is bonded airtight inside a filter casing made from steel. HEPA filters are delicate, they cannot be vacuumed or cleaned but due to the considerable surface area of the filter paper they will generally last 3 years or more when used with proper pre-filtration. HEPA filters must also have an airtight seal or gasket on the external face to prevent air from bypassing around the filter.

Air bypass is a common problem with air purifiers, where due to lack of a proper seal or filters are made from less than ideal sealing materials such as cardboard, paper or plastic, air bypasses around the filter resulting in efficiency being a fraction of the stated 99.97%. All InovaAir HEPA air purifiers are factory certified to filter 99.97% @ 0.3 microns efficiency.

NB: Most residential HEPA air purifiers sold in Australia do not conform to medical grade HEPA standards. There is no regulatory authority which monitors claims by manufacturers that HEPA filters sold in either vacuum cleaners or air purifiers are actually 99.97% efficient.

InovaAir offers ACTUAL 99.97% (Medical Grade) efficiency @ 0.3 microns.
While the majority of HEPA filters in home air purifiers on the market claim 99.97% efficiency – few achieve this because filters fail to seal properly and are not built to Medical Grade HEPA standards. Filters constructed from cardboard, plastic or polystyrene foam most commonly allow air to bypass around the filter because they do not have the structural integrity to create an airtight seal with a gasket. In keeping with Medical Grade standards, InovaAir only uses steel in the filter housing construction.

Ongoing Filter Replacement Costs:

Pre-filter6 months$50
H13 Medical-grade HEPA filter5 years$295
Optional 6kg carbon filter5 years$195

Note: Filter replacement intervals are based on continuous use.
Filter life will vary depending on what dust & chemical concentrations are present in the environment.

For replacement, filters are easily accessed by simply unlatching stainless steel latches and removing the top of the system.
