Where to Put Your Air Purifier

Many of you have realized the need for an air purifier, but probably wonder where to put it. Of course, if your allergy is severe, you will probably have to install a high-capacity air purifier that will be powerful enough to clean the air in the entire house or get an air purifier for each room.

But if one air purifier is enough, you should probably put it into the room where you spend the most time. Usually, it is your bedroom where you spend one third of your life sleeping.

Since air cleaners produce certain noise, it would be better to place them far from your bedside.


If you have pets, keep them out of your bedroom. Also, if you are allergic to animal dander, fur, and feathers, your air purifier will be especially useful in the room where your pets stay most of the time.

If you decide on purchasing another air purifier, it is probably a good idea to place it in the living where more than one family member can benefit from the clean air. If you work from home, you can place the next air cleaner into your home office.

There are some general tips as well – to achieve the best air cleaning performance, an air purifier should be put across the room from a heating or air conditioning unit. The airflow should not be blocked by walls or other objects, so it would be effective not to put it close to them.

If you like opening windows for a jolt of fresh air, consider placing your air cleaner far from the window so that airflows don’t interfere.

Keeping Dirty Air out of Your Car

Today, in our polluted, unnatural and chemicalized environment, the air outside is not very breathable, especially if you are on the road. Some drivers even have to keep their windows up to prevent the dirty air from entering their car.

It’s a good thing that you don’t have it anymore as there are car air purifiers that will clean the air in your car and get rid of odors.

Roadpro 12V Mini Air Purifier / Ionizer, Chrome

This little thing costs about 13 bucks but can remove dust, pollen, smoke and odor. The Roadpro 12V Mini Air Purifier draws power through the cigarette- lighter socket and features an illuminated tip and chrome finish. If you want a neutral-smelling car, with no smoke or unpleasant odors, this device will do it for you. However, you should be cautious if you have serious asthma because this air purifier emits ozone.

This air purifier is as cheap as they come – you can get for eight dollars. Moreover, for its price, it is just excellent at doing its job and removes fumes, unpleasant odors, pollen, dust and bacteria. However, there is one little issue – if you are prone to throat irritation, you should think twice about getting it as ozone can cause more frequent asthma attacks in those who suffer from asthma and lead to sore throats and breathing difficulty.


Portable Personal Air Purifiers – Pure Air to Go

We have already covered that air purifiers can be a real life saver for those who have breathing problems or allergies. But we cannot spend all the time indoors and when we go outdoors, we cannot take the clean air with us. It is good if we go to a forest with clean air to breathe but, more often than not, we end up breathing dirty air that can cause allergies. But there is a solution that can help you to enjoy pure air even outdoors and get protection from allergens, irritants and viruses that can threaten you outside – portable air purifiers.

But if you suffer from asthma, allergies or just don’t want to catch flu, you can probably overlook this inconvenience for the sake of clean air.

Air Purifiers for Pet Owners

The quality of the air in your home is extremely important for both you and your pets. Cats and dogs give off dander that can aggravate your allergy problems if you are allergy-prone. In addition, viruses, molds, pollen and bacteria accumulate in your house, making the air you and your pets breathe more odorous and less healthy. To making the breathing process for you easier, you will probably need an air purifier. We brought you the list of air cleaners that are designed to make the air in your house with pets more breathable.

Air Purifier Technologies: Electrostatic Precipitators

Electrostatic precipitator, also called electrostatic air cleaner, is a device that captures particulate matter from the flowing gas or air by giving them an electrical charge and collecting them in the oppositely charged collector plates. Ozone generators, ion generators and electrostatic precipitators work on similar principle of using electricity. Because of its resistivity and particle size distribution, electrostatic precipitator has a very high efficiency.

electrostatic precipitator 1

According to EPA (United States Environmental Protection Agency), there are two types of air cleaner that can remove particles from the air. These are mechanical air filters and electronic air cleaners. Mechanical air filters like HEPA (High Efficiency Particulate Air) work by capturing the particles on filter materials. Electronic air cleaners work by trapping charged particles in a process called electrostatic attraction. Electrostatic precipitator is a type of electronic air cleaner. source


How Electrostatic Precipitator Works?

When the dusty polluted air enters into the electrostatic precipitator, the particles in the air will be given a charge as it passes through the high voltage electrical field. The particles that have been given a charge will then pass through a series of collecting plates that are alternately charged. The charged particles are repelled by plates with similar polarity as the particles and attracted to plates with the opposite polarity. This attraction and repulsion of particles have the same principle to how a magnet works.

electrostatic precipitation works

The dual- stage electrostatic precipitator contains two parts, the collecting and the charging sections. The entering mist, grease, smoke, and other particulates in the charging section will pass through the ionizing wires which give the particles a positive charge. In the collecting section is the secondary electrical field, the negatively charged plates made from aluminum will attract the positively charged particles, causing them to stick into the plates and making the ejected air free of contaminants.

dual-stage electrostatic precipitator

Contaminants That Electrostatic Precipitators Remove

The electrostatic precipitator can remove dust, common allergens, and particulates. It is very efficient but its efficiency will degrade as the collector plates become dirty. However, charged particles that escaped the collecting plates may stick to walls or any objects in the house and soil them.

Below is a chart that shows the effectiveness rating of electrostatic precipitator air filters (the chart below is from an electrostatic precipitator with clean collection plates):

electrostatic precipitator chart



Electrostatic Precipitator Evaluation


– High efficiency of capturing 99.9 percent of airborne particles.

– Quiet operation

– Changes in temperature and pressure are small

– Can trap tough materials like tars and acids

– Can withstand corrosion

– Don’t need high power for cleaning

– It is possible to have a huge flow rate


– Initial cost is high

– Particles with very low or high resistivity are hard to trap

– Have the potential to emit dangerous levels of ozone according EPA (United States Environmental Protection Agency) source

– To maintain efficiency, collecting plates must be kept very clean


Buying Electrostatic Precipitator Air Purifier

Consumer Reports for the past 15 years has recommended some air purifier that uses electrostatic precipitators as a filter. They recommended Aprilaire 5000 and Friedrich C-90B because it only emits a small amount of ozone and they have a low yearly maintenance costs. Electronic air purifiers like ion generators and electrostatic precipitators can produce some byproduct like ozone. Ozone is a known lung irritant; it can decrease lung function and cause adverse health effects.

                                                                   Aprilaire 5000        Friedrich C-90B

However, Consumer Reports now believe that every air purifier products that give off even tiny amounts of ozone (fewer than 50 parts per billion) are not the best choice for you. Research is warning against adding ozone to the indoor air. They also believe that there should be more research conducted to know the effects of low level exposure to ozone.


Best 5 Activated Charcoal Air Purifier Reviews

If you are not an owner of water purification system or an aquarium, you might be surprised how come an activated carbon is used as an air purifier filter. The use of carbon filters for water purification is considered as the oldest method of water purification.

Activated Carbon


It is used by people for centuries to filter impurities from drinking water. In the industry of aquarium, activated carbon is currently one of the most effective adsorbents used and the largest selling maintenance product. It is used to remove dissolved organic molecules, chloramines, chlorine, and some heavy metals. It is also used to remove residual dyes medications like dyes and antibiotics.


clean filtered water 

What is an Activated Carbon?

Activated carbon, also known as activated coal or activated charcoal is derived usually from charcoal. It is a form of carbon which has a small charge of electro-positive added to it. The added charge makes it more attractive to impurities and chemicals that are negatively charged. Charcoals used in making activated carbon are made by burning coconut husks, nutshells, hardwood, and other materials that are carbon-based.


To make it available for chemical reactions and adsorption, carbon is also processed to have an extremely large surface area and make it very porous. Through the help of nitrogen gas adsorption, it is determined that with only 1 gram of activated carbon usually has a surface area of 500 square meters or 1/10 the area of a football field and 1 pound of activated carbon has 200 miles of fissures and pores with an area of 4 million square feet.


Activated carbon, especially the granulated one combined with packed tower aeration method is recognized by EPA (United States Environmental Protection Agency) to remove carbon tetrachloride from drinking water to below 0.005 milligram per liter or 5 ppb. source

Activated Carbon Filter Used in Air Purifiers

Activated carbon is frequently joined with other minerals like zeolite when used in air purifiers. Zeolite can act as a chemical sieve and a filer for absorbing molecules and ions.


In several units of air purifier, the carbon is impregnated with potassium iodide and mixed with impregnated active alumina in order for the absorbent qualities to increase. People with MCS (Multiple Chemical Sensitivity) will benefit from these air purifiers because they can absorb formaldehyde found in furniture upholstery, wood paneling, and carpet. These air purifiers can also remove perfumes and household cleaning chemicals, making your house more fresher and breathable for elderly, children, babies, asthma sufferers, and people in general.

Type of Air Contaminants Activated Carbon Air Filters Can Remove

Most fumes from household cleaners, cooking, and organic odors can be removed or reduced by activated carbon filters. It can also remove VOC (Volatile Organic Chemicals), solvents, radon, THM (trihalomethane), benzene, chlorine, herbicides, pesticides, and other manmade chemicals.

Below is a chart which rates the activated carbon filter’s performance on its ability to remove the following contaminants:

chart contaminants carbon filters remove source


Choosing the Right Activated Carbon Air Purifier

When buying an activated carbon air purifier, you should choose a filter with a big amount of activated carbon. A lot of low quality air purifiers sold in the market contains only a very tiny amount of activated carbon. These air purifiers will perform poorly compared to those with bigger volumes of activated carbon.

Another point to consider is whether the activated carbon media can be replaced without changing the whole containing cartridge. Complete cartridge unit is much expensive compared to bulk media.

Do Air Purifiers Really Work?

We used to think that the air outside is dangerous to our health a decade ago because of the increasing pollution caused by burning fossil fuels and common organic pollutants. As a result, we stay inside our house worry free and feeling secured.

Well, the truth is that the air inside your home is actually more polluted than the air outside. The United States Environmental Protection Agency’s Office and Development conducted a study and found that the levels of about a dozen organic pollutants inside homes are two to five times higher compared to the air outside.



What types of pollutants can an air cleaner remove?

Air purifier can remove the following indoor air pollutants:

1. Particulate matter

  • viruses


  • bacteria


  • molds


  • dust mites


  • particles created from combustion appliances like cooking stoves

           cooking stove

  • tobacco smoke


  • animal dander

           animal dander

  • pollen


  • smoke


  • dusts



2. Gaseous pollutants come from the process of combustion and from using building products:

  • pesticides


  • cleaning products

           cleaning products

  • varnishes


  • paints


  • adhesives


  • cooking stoves

           cooking stove 2

  • tobacco smoke

           tobacco smoke

  • vehicle exhausts

           vehicle smoke


To better answer the question “Do air purifiers really work?”, we must first determine whether the United States Environmental Protection Agency (EPA) supports the use of air purifier.

According to the United States Environmental Protection Agency (EPA):

  • Air cleaning may be useful when used along with source control and ventilation, but it is not a substitute for either method.
  • The use of air cleaning devices may help to reduce levels of smaller airborne allergens or particles.
  • While air cleaning devices may help to control the levels of airborne allergens, particles, or, in some cases, gaseous pollutants in a home, they may not decrease adverse health effects from indoor air pollutants.
  • The use of air cleaners alone cannot ensure adequate air quality, particularly where significant sources are present and ventilation is insufficient.
  • Clinicians frequently recommend that patients who have asthma or allergies use HEPA air filters in HVAC systems or in portable air cleaners.
  • Regardless of how efficient and effective air- cleaning devices are in removing pollutants, a question still remains about their ability to reduce adverse health effects.
  • An air cleaner’s ability to remove some airborne pollutants, including microorganisms, is not, in itself, an indication of the air cleaner’s ability to reduce health symptoms.


Now to answer the question “Do air purifiers really work?”, the answer is YES. But how well they perform will depend on the air purifier brands. While air purifiers are not enough to combat the air pollution inside our homes alone, the United States Environmental Protection Agency (EPA) still consider them as an option if the ventilation method is not applicable in some weather conditions or when the contaminants level outside is undesirable.

Ionic Air Purifiers

Staying at home does not guarantee you are safe from air pollutants. Most of the time, people stay indoors for relaxation and free from air pollution. Unfortunately, even air at home is not that safe. They hide in your walls, curtains, carpets and even in your clothes. These pollutants stay usually in closed house and kitchens or offices.


There is a product that helps you minimize pollution within your own house. It is what they call Ionic Air Purifier. How does this work?

An ionic air purifier is based on scientific technology. The technology binds the ionic particles to the pollutants in the air which makes the pollutants heavy to remain in the air and so it settles down below the surface of room where your equipment was set up. So you will be at peace since you are assured of clean air at all times when you are at home

How is this maintained? This technology does not need to change filter. It is for lifetime. This would mean, performance will not change in the long run due to clogging of filters. Fantastic isn’t it? Plus the fact that it can reduce the money you will set aside for your health budget. You would feel comfortable and relax if worry for health is set aside.

ionic air purifier

There are brands in the market to choose from. All offer protection for the entire family. This includes elimination of airborne contaminants which include pollen, dust, smoke (especially cigarette), bacteria, germs and other allergens. It can also remove cold & flu viruses and pet dander. This technology turns smog and ozone to pure oxygen! And best, it is silent. All these are done in about 30 minutes.

Ionic air purifier comes in different size and style. Some are bigger that would accommodate larger area and some also are portable so it can be moved from room to room. There are units that have two cleaning levels which mean you can choose low or high settings. All you have to do is check what brand would best suit your needs.
