What is medical grade HEPA?
Medical grade HEPA filters are commonly used in pharmaceutical manufacturing and electronic control rooms because they have a greater particulate retention rate. This means medical grade HEPA filters are more efficient in removing harmful toxins from the environment.
Why are air purifiers bad for you?
Specific effects may include throat irritation, coughing, chest pain and shortness of breath, as well as an increased risk of respiratory infections. Some ozone air purifiers are made with an ion generator, sometimes called an ionizer, in the same unit. You can also buy ionizers as separate units.
How long do HEPA filters last?
It depends on how much you use it, but regular use based on an average cleaning schedule should keep it doing the job for between 24 to 36 months.

What is a HEPA 14 filter?
HEPA 14, also called H14, is the filter class commonly used to filter out bacteria, viruses, and other airborne contaminants in sensitive healthcare environments.
Is True HEPA the same as HEPA?
The main differences between HEPA-type and True HEPA filter are the filtration efficiency. In general, HEPA-type filter has a 99% efficiency rate of capturing particles as small as 2 microns. True HEPA filter up the game with a better 99.97% efficiency rate at particles as small as 0.3 microns.
What is a true HEPA filter made of?
The True HEPA filter is mostly made of the highly dense paper, which is composed of very thin fibers with distances between 0.3 and 2.0 microns. The fibers are distributed randomly and oriented in all directions.
What are the disadvantages of air purifier?
The disadvantages of air purifiers are:
- You need to have the windows closed.
- Regular maintenance.
- Old filters worsen air quality.
- An air purifier needs free space around it.
- Air purifiers are not entirely quiet.
- Ozone production.
- It does not solve all indoor air quality problems.
- Many air purifiers do not remove odors.

Is Covid an airborne virus?
Spread of COVID-19 occurs via airborne particles and droplets. People who are infected with COVID can release particles and droplets of respiratory fluids that contain the SARS CoV-2 virus into the air when they exhale (e.g., quiet breathing, speaking, singing, exercise, coughing, sneezing).
Does iWave produce ozone?
iWave products are patented ion-generating devices that produce the highest available ion outputs and do not create ozone or harmful byproducts, which are different than current ionizers on the market.
How do you ventilate a room in Covid?
Ventilation in Homes Refer to CDC and ASHRAE guidance on isolating COVID-19 patients and protecting people at high risk. Opening windows and doors (when the weather permits), operating window or attic fans, or running a window air conditioner with the vent control open increases the outdoor ventilation rate in a home.
