You may not realize how dangerous poor air quality can be. The long-term effects of air pollution contribute to the deaths of more than 4.2 million people around the globe every year, including heart disease, strokes, lung cancer, and other serious respiratory conditions. Two most commonly used air purifiers include HEPA Purifier and Ozone Generator. Here is everything you need to know about HEPA Purifier Vs Ozone Generator features. You can go through the detailed description of both and make an informed decision.
Overcrowded urban areas often suffer from these problems, but poor air quality isn’t only confined to busy cities. Airborne contaminants, bacteria, allergens, viruses, and diseases are common everywhere.
Pollutants pose health risks when inhaled. Air treatment can reduce these risks. Together, we’ll discuss the positives and negatives of the most popular purification systems used today.
Today, ozone generators and HEPA filters are among the most popular air purifiers. These two methods are sometimes combined into one purifying unit to make the air as decontaminated as possible.
Gas masks featured in WWII and the Manhattan Project contributed to the development of HEPA purification technology. HEPA air purifiers have been used for decades as a method for purifying indoor air.
The HEPA filter separates microscopic particles from the air by straining out microparticles. Filters that meet HEPA requirements must be able to filter 99.97% of particles with diameters less than 0.3 *m, with increased efficiency for particles larger and smaller than that. What is the process of installing these filters?
By drawing in polluted air with the aid of a fan, HEPA purifiers work. In essence, the air is forced through a tangle of fiberglass fibers to catch airborne particles.
Especially important is the diffusion component, which traps particles smaller than 0.1 μm. Due to the small size of these particles, they are unlikely to accumulate on any of the fibers in the filter. As their “flight path” is interrupted by other particles, their trajectories become zigzagged, making the other two methods less effective because the particles are more likely to get caught by those methods.
Air flows back into the room after passing through the filter, and the purifier draws in more polluted air to purify. The purifier will gradually filter the majority of the air in the room, resulting in dramatic reductions in particulate matter.
Pros of HEPA Purifiers
There are several reasons why HEPA purifiers remain a popular household item. Filters that trap more and more airborne particles are more effective with HEPA purifiers at reducing particle pollution, and HEPA purifiers do not release any harmful byproducts.
It’s also worth mentioning that HEPA purifiers come with the benefit of combining filtration with other methods of purification. Several HEPA purifiers feature UV pre filters designed to kill microbes before they reach the HEPA filter.
Cons of HEPA Purifiers
Particulate matter is effectively removed by HEPA purifiers, but they also need frequent maintenance. In order to keep your unit in good working order, you will need to replace HEPA filters regularly. The cost and inconvenience of replacing a filter will increase if you live in a heavily polluted area.
By restricting air flow through the unit, HEPA filters can also increase energy costs in central air conditioning or ventilation systems. Moreover, HEPA filters are not much effective to remove odors or microbes (at least not reliably).
Using an ozone generator, particulate matter is instantly deodorized, disinfected, and killed. A similar electrical charge is applied to the air by ozone generators, but this charge breaks apart oxygen molecules which later bond to form ozone. Commercial settings frequently use ozone generators due to the rapid purification rate.
We call ozone (a molecule of three oxygen atoms) the molecule resulting from the reaction of oxygen molecules with either corona discharge or UV light. By “donating” an oxygen atom to surrounding molecules, ozone is highly reactive and changes the chemistry of its surroundings.
Pros of Using an Ozone Generator
Microbes can be killed by ozone generators in industrial settings and spaces without occupants.
Biological contaminants are also effectively treated using the ozone generator machine. To be effective, ozone levels would need to be managed according to public health standard to eliminate biological contaminants. Due to this, ozone generators can be used in spaces with no occupants.
Using ozone, which is generated on site from oxygen, can be used in a wide range of applications, eliminating the need to transport hazardous chemicals. Ozonation can save the environment, time, and money in a number of ways. As an excellent alternative to harsh caustic chemicals, ozone is much safer and healthier to use. The ozone oxidation can be used in many different applications for disinfection or cleaning. Using ozone to perform the same job as the HEPA filters, while working in cold environments, reduces energy consumption and saves money.
Other Advantages of Ozone
- Ozone is clean and environment-friendly, its only by-product is oxygen
- Ozone is extremely effective as a disinfectant at relatively low concentrations
- Ozone permits recycling of wastewater
- Ozone reduces Biological Oxygen Demand (BOD)
- Ozone is generated on site eliminating the transporting, storing and handling of hazardous materials
- Ozone is very inexpensive to produce and has an unlimited supply
- Ozone is much safer for employees than any conventional chemicals
- Ozone is chemical-free; it produces NO toxic by-products
- Ozone has full FDA-approval for direct-food contact application
- Ozone extends the shelf life of food products
- Ozone is 51% more powerful on bacterial cell walls than chlorine
- Ozone kills bacteria 3000 times faster than chlorine
- Ozone is the most powerful broad spectrum microbiological control agent available
- Ozone eliminates the use of hot water and conventional sanitizer
- Ozone virtually eliminates all chemical usage
Cons of Ozone Generator
The ozone generators should be used in spaces with very good ventilation and away from areas frequented by pets and humans.
Many businesses and general consumers today use ozone generators for air treatment, which are highly effective at removing particulates. Ozone generators eliminate odors, dander, smoke, and dust effectively.
In contrast, HEPA filter purifiers have difficulty capturing and neutralizing VOCs, viruses, bacteria and particulate matter smaller than 0.3 microns. To achieve better results, HEPA is sometimes combined with an ozone generator. All things considered, the ozone generator is a better option for long term.
