Stylish design and natural fresh air best interpret a high-quality home. But air pollution brings us serious and invisible life threats. Polluted air can not only be a direct vector of respiratory infectious diseases but also be contaminated with other vectors of disease transmission. The global average of 2.8 million people die every year due to indoor environmental pollution! So how to manage indoor air pollution control?
Activated Carbon Adsorption
Principle: Use the high surface area of activated carbon or carbon fibre surface to chemically adsorb harmful chemical gases in the air.
Advantages: simple to use, in a short period (5-7 days) can adsorb a certain amount of pollutants, mainly for volatile organic compounds and odours, the product itself has no secondary pollution.
Disadvantages: no purification effect on microorganisms, with the temperature, wind speed rises to a certain level when the adsorption of pollutants may be free.
Air freshener
Principle: release a high concentration of fragrance in the space, affecting the sensitivity of the sense of smell to other odours.
Advantage: It can cover up and disguise the odour, and solve the problem of air odour in a short period and on a small scale from the olfactory aspect.
Disadvantages: low toxicity itself, only plays a role in masking odour, no effect on pollutants, bacteria and so on.
Negative ion purification
Principle: eliminate formaldehyde through a chemical reaction, which can reduce and reduce formaldehyde pollution in indoor air to some extent.
Advantages: relatively simple to use, can make the particles of pollutants gathered, and settled, have a certain effect on the purification of air.
Disadvantages: the process is slow, disinfection is not complete, the chemical substance pollutants do not work, easy to accumulate dust.
Ozone purification
Principle: The oxygen atoms in ozone can release active oxygen very easily, which can quickly have a chemical reaction with the harmful gases in the air.
Advantages: Some organic substances in the air are oxidised directly into carbon dioxide and water, and the effect is obvious in a short period.
Disadvantages: It has a certain degree of toxicity, is not entirely suitable for inhabited environments, and the use of an environment more than 30 ℃ may cause cancer.
Air Purifier
Principle: Blowing out negative ions to filter out particles, suspended particles and dust at the import and export of the machine.
Advantages: a small range, a short period of air smoke, tiny dust particles have a better filtering and purifying effect, the new air purifier has a certain effect on the toxic and harmful gases in the air.
Disadvantages: limited effect on toxic and harmful gases, the filter needs to be replaced constantly. No surface bactericidal function, energy consumption, open to be effective.
Diatomaceous earth
Principle: diatomaceous earth particles have countless tiny pores on the surface, with strong physical adsorption properties and ion exchange properties.
Advantages: absorption of free formaldehyde, benzene, radioactive substances, pets, smoking, and household waste produced by the odour, sound absorption, heat insulation, and thermal insulation.
Disadvantages: bacteriostatic but no antibacterial function, with the increase in the number of years of use, the effect is reduced. Saturated with the temperature rise secondary release of harmful materials.
Plant
Principle: adsorption of dust, metabolism will absorb harmful gases in the air, synthesis of other substances in the body.
Advantages: environmental protection, the role of the environment to improve the release of oxygen to keep the air fresh air.
Disadvantages: only play an auxiliary role, pollen, flowers easily allergic to people and respiratory disease patients are not favourable.
Formaldehyde Capture Agent / Formaldehyde Remover
Principle: Eliminate formaldehyde through chemical reaction, can reduce and reduce formaldehyde pollution in indoor air to some extent.
Advantages: Can reduce and minimise formaldehyde pollution in indoor air to some extent within a short period.
Disadvantages: only for formaldehyde, benzene, ammonia, TVOC, bacteria, etc., no effect on leather, paint film and other surface damage.
Photocatalyst
Principle: The representative is a photocatalyst. It can produce active oxygen and hydroxyl radicals with a strong oxidising effect to oxidise harmful substances into carbon dioxide and water.
Advantages: fast removal speed, better effect, long duration, basically does not produce secondary pollution.
Disadvantages: theoretically, as long as the product is not damaged, it has been effective, but most of the domestic photocatalyst enterprises conceptual speculation.
