If you are looking for an air purifier, you should see the word "no filter" appear very often (especially the most famous one, Ionic Breeze). The filterless purifiers applying an electrical charge opposite to the incoming air, which can retain dust and dirt on a grid. The grid should be cleaned often enough, especially if you have smokers in your life.

Another product used in this method is ozone. This product is considered hazardous to health by some people: it can irritate especially those suffering from respiratory disorders. Be careful not to let the purifier running too long depending on the size of the room (see the manual of the purifier).
The air purifiers without filters to avoid large expenditures in filters. However, the initial price of the purifier can be high. Unlike other purifiers, they are quiet so you can make them work while you sleep.
If the cost of filters and noise barriers for you in buying a purifier, ask about the unfiltered purifiers.

An air purifier is supposed to make the air cleaner and more breathable. But how to know whether it will do really? Please have a Kanomax 3887 and particle counting can begin.

This portable device is the amount of particles of three different sizes simultaneously. The result is given in cubic meters. Connect the device to your computer and transfer the data to see the results and compare them. This device can be used to evaluate the air in your home but also that of your working environment.

The classifications considered a normal living space with air natural environment "dirty" with three types of dust: heavy (your dusty furniture), air (dust floating in the air), suspended (dust tiny ). If you or a family member suffering from health problems, you need to get rid of dust and biological contaminants (mold, fungi, viruses, bacteria and any infectious particle) of your home.

Before investing in an air purifier, consider the state of the air in your home with the Kanomax. It will help you find the particles in your air that you can neither see nor smell. The manufacturer can provide you with this tester.

What budget should I allow for the initial price and maintenance costs?

Inquire about prices of products is one thing. But if the filter or other elements must be changed regularly, find out how often this replacement must be done and how much it will cost. For example, HEPA filters cost at least € 75 and change every year or every 18 months. Electricity consumption is another factor to consider. Learn about consumption in watts of the purifier. A consumption of more than 100 watts can increase your annual electricity bill of 100 € (according to the tariffs applied by the company).

To what extent this book is it noisy?

A high consumption of electricity will perhaps purify a volume of air greater, but will also certainly more noise. If you care about noise, try to test the product before purchasing. Otherwise, some products offer a money back guarantee so you can try the product at home and bring it back if you are not satisfied.

Which parts of your home you want to purify?

Want to remove odors from your pet in a particular room or protect your child's bedroom allergen? Think about the amount of space you want to purify. Most cleaners are portable and can be moved from room to room. You can also buy several purifiers. Otherwise, another option awaits you: a filter for your heating and cooling. This method will purify a larger space, although it is not as effective as the purifier unit in terms of purification. Moreover, in general, the filters do not offer multiple technologies. On some purifiers, the covered area is specified. See "How the effectiveness of the purification is assessed? "

How the effectiveness of the purification is assessed?

It assesses the effectiveness of purification by observing the type and quantity of particles captured and the volume of clean air over a period of time. Filters are classified by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (an international organization related technical geniuses of heat and climatic known as ASHRAE).

The classification is made according to two criteria: 1) Initial Staining Dirt Efficiency (efficiency on particles present messy) assesses the extent to which a filter removes particles that messy grease, allergens and tobacco tar, 2) L 'Average Arresta Test calculates the percentage of dust, hair, tissue and other large particles that can remove the device.

The Association of Home Appliance Manufacturers (an association of manufacturers of household products) or AHAM tests the effectiveness of purifying the Clean Air Delivery Rate (CADR). This method involves measuring how many cubic meters of air per minute are cleaned of 3 particles of different sizes: small (smoke), medium (dust) and larger (pollen). Over the purifier is, the less it takes to eliminate these particles. Purifiers recognized by the Framework will be those approved by the AHAM.
Apparatus for measuring the quality of indoor air

The spring temperatures make you want to open all the windows and let fresh air into the house. Unfortunately, that fresh air can be as sinful as the stifling air of your home. All kinds of pollen it carries can make it unhealthy for you and your family.

An HVAC contractor installs a new home monitoring device called Air Advice for a few days. It saves all the characteristics of the air in your home ... its humidity, temperature and the types and quantities of chemicals and particles. All this information is transcribed into a report that will help you with the help of your contractor, to decide what products you need to enjoy a healthier atmosphere.

If your house is old, it is possible that your ducts are clogged or filled with dust and debris. Just clean the ducts will help you a lot. If your house is brand new, the pipes are probably closer, which is perfect for limited electricity bills and heating, but bad for air quality.

When purchasing, pay attention to the MERV product. The Minimum Efficiency Reporting Value (minimum capacity efficiency) is an evaluation of filters. That's where the term comes HEPA become so commonplace it stands for High Efficiency Particulate Air (High efficiency particulate air). The HEPA filter is coming out top of ratings. Some industry experts say that the HEPA filters eliminate 100% of particles of at least 0.3 microns.

An effective purifier helps you combat your allergies

If you are allergic to animals, dust or pollen, an air purifier can help relieve symptoms. Environmental equipment such as air purifiers and filters, including HEPA filters, you can be less exposed to these particles, reducing their number. They can therefore help you in your struggle.

The American Lung Association (American association of lung disease) advocates for people with asthma to a HEPA filter in their room. The Mayo Clinic (care facility recognized American world) recommends systems bring home ventilation air filters. The ionic systems using the attraction of negative ions to purify the air. Any system that is brewing in the air particles to which you are allergic is a bad system.

If you suffer from seasonal allergies or respiratory problems because of elements present in you, try using an air purifier to relieve symptoms. This is a good way out of this hell.

If you or a family member suffers from allergies, you should bring an air purifier mechanical or electronic to remove particles from the air. The HEPA and ULPA collect and dispose of all these particles. The purifiers are electronic limit to remove these particles through their negative ionizer. It is then up to you to collect or not when you clean, vacuum or dust made. If you want to get rid of particles of chemicals, smoke or gas, you'll need an air filter carbon for other types of filter does not address these pollutants.

However, a carbon air filter can remove the odor of chemicals as ozone generators can eliminate most odors. If a smoker in your family or your dog or cat does not smell the rose, consider instead buying a purifier with ozone generator built. However, if your goal is simply to eliminate the odor, you probably need is an ozone generator. Remember that even when the ozone released its own smell, so be sure to limit the amount of ozone emitted. If you want to kill viruses, germs, bacteria and fungi in your environment, UV light is probably the most effective. Although it can not destroy all microorganisms, it will limit the amount present in the air. Some mechanical filters have a UV lamp that traps microorganisms and prevent them from reproducing. It is a brilliant idea.

The best may be to buy an air purifier performance that blends several of these elements. I suppose you can doubt that it will not be given ...

Air Purifier mechanical

The mechanical air purifiers are equipped with fans that draw air into a series of filters.

HEPA Filter:

The HEPA filter or High Efficiency Particulate Air was created by the government during the Second World War to reduce the amount of dust present in radioactive nuclear plants. The HEPA filter removes 99.97% of air particles with a diameter of 0.3 microns. The HEPA filter consists of a continuous sheet of fiberglass special folded "V" with aluminum separators between the folds. These filters remove allergens such as dust mites, pollen and mold spores.

HEPA filters do not retain particles smaller than 0.3 microns and does not kill viruses and germs. However, they eliminate much of the bacteria in the air. These particles are captured and can not return to the air. This shot is so effective that some micro-organisms will eventually grow and reproduce in the filter. Another disadvantage of these filters is that they can not remove particles too far apart. Moreover, they have no effect on the chemical vapors, gases, cigarette and other odors.

ULPA Filter:

ULPA filters or Ultra Low Penetrating Air, were initially designed for use in hospitals. They are now also available for home use. They have a medium microfiber glass that can hold 99.99% of particles of at least 0.1 micron. Although the filter can remove particles smaller than HEPA, he shares the other disadvantages What all filters.

Air filter carbon

These filters have pores of molecular size very absorbent. These pores form a strong fabric which stick liquids and odorous gases. This filter is the most absorbent on the market: it holds the gas, cigarette smoke, odors and chemical vapors. Once the particles in the air filter carbon, they can not return to the air. This filter has the same drawbacks as the other filters mentioned above. On the other hand, it does not remove particles such as dust, microorganisms and other allergens.

Electronic Air Purifier

The electronic air cleaners use an electrical charge to trap particles suspended in air.

• Purifier Electrostatic it positively charged particles caught by the camera. These particles are then attracted collectors aluminum located in the device. Only particles passing through the electrostatic air purifier is removed. It is therefore difficult to purify an entire room.

• Electret Air Purifier: a special filter, called electret, is charged with electricity so that particles entering the device cling to the filter. The disadvantages of this device are the same as those mentioned for the electrostatic purifier.

Ionization Purifier • Negative: This type of purifier emits negative ions throughout the room in different ways (one way is the electricity that flows through steel needles. This system is called needle points). Thus, the negative ionization purifier can be effective on larger areas than cleaners who only draw air into them. The negatively charged ions change the polarity of the particles in suspension so they bind together. When they become too heavy, they fall down.
• This type of purifier does not catch the particles, it is simply so that you can not smell them. You can pick up the particles, either by vacuuming or by dust. A drawback of these purifiers is that they can dirty their surroundings because of the negative ions.

Other types of air purifier

Germicidal UV lamp that is capable of killing germs, viruses, bacteria, fungi (mold) that pass through the bulb. This lamp has no effect with cons on particles suspended in air.

Ozone Generator: Ozone can destroy some bacteria and some chemicals, including those that give off an odor. It helps to get rid of many odors, including that of cigarette smoke. These generators are not acting on particles suspended in air and can release their own smell, that of ozone. A high concentration of ozone in the air can cause irritation of eyes, nose or throat. It is better to extinguish the purifying from time to time.
