Cost of formaldehyde removal

Formaldehyde is often used as a preservative for dead 除甲醛費用 things such as frog in biology classes. But if you live with these couples, you know firsthand that they can be cruel. Here are 5 information about this chemical that can help.

What the Environmental Protection Agency has to say – the U.S. Environmental Protection Agency (US Environmental Protection Agency) speaks about acceptable levels of formaldehyde. They set high levels, as above. 1 ppm (parts per million), knowing that new homes that use a large number of pressed wood products are likely to level 3 ppm or more.

This quote directly from the EPA reads: On December 3, 2008, the EPA’s Office of Prevention, Pesticides and Toxic Substances issued a preliminary notice of the proposed regulations (ANPR), which describes the EPA’s first steps to investigate possible measures to protect against the risks of formaldehyde from pressed wood products used in industrial homes and other locations…

No fumigation delay – it depends on the amount in your home. Sensible odors may disappear after a few weeks, but often weaker secretion can persist for months. In many mobile homes, when sediment deposits occur, cracks and ruptures of joints occur, allowing even more vapors in the air to come out.

Everyday objects that contain it. You may be wondering what these pairs emit. The answer is more than shocking than you can imagine. Formaldehyde is often used as a component of paints, coatings, adhesives and adhesives. It is also found in pressed wood used for black floors, furniture, cabinets and shelving. It is also used to give many tissues a resilience to constant pressing.

Effective prevention – the use of non-chemical organics in the manufacturing process is the best way to avoid chemical emissions. These softer and gentler products are appearing on the market more and more every day.

For example, there are paints low in VOC (volatile organic chemicals), organic mats and fabrics that have not been chemically processed. Natural wood instead of pressed, natural mats and fabrics – all this is more accessible and more healthy.

These natural and organic products can be a little more expensive, but the harm that chemicals in the air can do to your health is even more expensive, not only in terms of the cost of health problems that may arise, but also how they often affect your quality. Life.

Elimination – you can remove the vapors by sucking through the air, pushing it or filtering it. A fan throughout the house can be effective, but it also sucks any pollutants from outside the room. Blowing the air with a powerful fan is also a great short-term solution. But any of these ideas will only work as long as the temperature and external conditions are moderate enough for this to happen.

Sharing internal air with outdoor air can remove vapors, but if the outside air is very hot or cold, you become impossible to live in it because the temperature is impossible to control. But by filtering the air with a purifier specifically designed to remove formaldehyde vapors, you can maintain a stable temperature and enjoy clean air. This is the best proactive, non-invasive and long-term solution to an existing problem.

Indoor air pollution is a serious problem. According to the Environmental Protection Agency (EPA), indoor air pollution levels are two to five times higher. In some buildings without proper ventilation, indoor air can be 100 times more polluted than the air outside! In fact, modern buildings are built for energy efficiency reasons. However, the airtight joints that make a low-energy home also delay pollutants. In addition, the average American breathes indoors nine out of ten, so make sure that the air in the room does not contain allergens and other contaminants.

Air purifiers remove allergens, toxic chemicals and other dangerous pollutants. This article explains why people use air purifiers, how they work, which air purifiers should be avoided and how to choose the best air purifier for your needs.

Common indoor air pollutants

What is the source of indoor air pollution? As for organic pollutants, mold and dust mites are everywhere – and these are the two most common causes of allergic rhinitis (hay fever) all year round. Pollen is also a poisonous allergen that always penetrates your home because it is so small and sticky. If you have pets, they are sure to spread their dander in every nook and cranny of your home. There are also many viruses and bacteria in the air.

Although they are not organic allergens, volatile organic compounds (VOCs) cause many people allergic reactions and other health problems. VOCs include formaldehyde, perfume, pesticides, solvents and cleaning products. VOCs can enter the air through chemical exhausts of furniture, new carpets, glue, plastics and various building materials. In addition, many volatile organic compounds are known carcinogens (carcinogens).

Environmental pollutants such as cigarette smoke, carbon dioxide, carbon monoxide and nitrogen dioxide can also be present indoors, as well as toxic heavy metals such as airborne lead, mercury vapors and radon.

How air purifiers work

HePA air purifiers use the HEPA air filter developed by the Atomic Energy Commission in the 1940s as a means of filtering out radioactive pollutants. HEPA filters set a standard for air purifiers: to be classified as HEPA, the filter must detect at least 99.97% of contaminants measuring 0.3 microns or more. The best-selling air purifiers with HEPA include the Austin Air Purifier, available with the highly efficient Adsoprtion Gas Filter (HEGA), and air purifiers from I’Air, Allerair, Blueair and Honeywell.

Activated charcoal filters remove gases, odors and chemical toxins. Charcoal is “activated” in oxygen processing, opening millions of tiny pores to attract and absorb chemicals. Coal filters with impregnation are treated with an additional chemical, usually potassium iodide or potassium permanganate; These chemicals, known as chemosorbents, improve the ability of the coal filter to capture VOC and other chemically active gases.

Electrostatic filters use an electrostatic charge to attract and capture contaminants on the collector plates. These filters are great for people who don’t want to worry about replacing HEPA filters, but if prefabricated plates aren’t cleaned often, they quickly lose their effectiveness. Also keep in mind that some electrostatic filters secrete ozone, which is known to irritate the lungs and can cause severe irritation in some people with asthma or allergies. The Friedrich air purifier is by far the best electrostatic air purifier, as well as one of the best air purifiers in previous Consumer Reports rankings.

Filters with a charged environment give the contaminants an electrostatic charge before they are assembled in a traditional filter. Filters with a charged environment are generally quite effective, but like electrostatic filters, they quickly lose effectiveness and may require frequent and expensive replacement. Some charged air filters also emit ozone. The advantage of filler filters is that they are quieter and more energy efficient than HEPA air purifiers. The Blueair air purifier is the busiest media filter that does not emit ozone.

Where and how to use an air purifier

If you are allergic (especially if you are allergic to dust mite), your bedroom is the best place for an air purifier. Clean air in the bedroom is very important as you will spend about a third of your life there. If you are allergic to pet dander and you have pets, you can install an air purifier in the room where your pets spend the most time and prevent them from getting into the bedroom! Also, don’t put an air purifier in the corner of the room; it must be at least a few metres away from the walls for maximum airflow.

For optimal performance, the air purifier must work constantly. Most air purifiers have high and low settings. Even when you’re going on holiday, we recommend leaving the air purifier in the shade. Otherwise you will return to a house full of polluted air! If you are concerned about your electricity bill, check how much energy the air purifier uses before buying it. Typical HEPA air purifiers can run from 50 to 200 w. For comparison, a regular lamp consumes about 60 W, and a regular computer – about 365 w.

Air purifiers to be avoided

Avoid ozone generators and ionizing air purifiers. These air purifiers create ions that attract pollutants; However, a lot of pollutants enter the air, which often leads to dirty stains on nearby walls. Ozone generators and ionizing purifiers not only do not clean the air properly, but also emit ozone. Ozone, a staple of smog, has the potential to cause severe asthma attacks.

In addition, David Peden, a researcher at the Center for Environmental Medicine and Lung Biology at the University of North Carolina, has studied how ozone exposure can worsen the allergic reaction of people allergic to dust mites, and its results show that ozone causes asthma. the condition is worse. Reaction. The EPA has warned consumers against using ozone generators, and Consumer Reports recommends eliminating the latest version of the Ionic Breeze quadra, despite the addition of OzoneGuard, a device designed to destroy part of the dangerous ozone emitted by Ionic Breeze.

Consumer Reports notes: “Our air purification tests show that Ionic Breeze with OzoneGuard poorly removes smoke, dust and pollen from the air when it is new and after 500 hours of continuous use” and “Ionic Breeze with OzoneGuard always adds ozone to the air. .

How to buy the best air purifier

The air purifier market is huge and full of confusing and often misleading advertising programs. When choosing an air purifier, you should first consider the type of pollutants that you are trying to remove. For example, if you have a problem with cigarette smoke, make sure your air purifier is able to remove vapors, volatile organic compounds and other gases.

You may also want to consider the following factors before buying an air purifier: area coverage (make sure that the specified air purifier area is about the same or slightly larger than the space you will use); ACH rating (air exchange per hour – this number indicates how often an air purifier can replace all air in a particular room); CADR (the speed of clean air diffusion shows the amount of purified air and the quality of its purification); The price; How often you need to change filters and how much they cost; The sound level of the air purifier Energy consumption If it releases ozone; Additional features (such as a light filter replacement light) Manufacturer’s reputation and a guarantee.
