Working of the HEPA air purifiers

The HEPA air cleaners work by filtering the allergens in the air through a HEPA air-filter that traps the particles allowing the clean air to return to the atmosphere. The larger number of times that the air passes through the HEPA filters, the better and cleaner becomes the quality of the air. So till date the HEPA purifiers have proved to be the most tried-and-true air-cleaning instruments. The best part about HEPA air-purifiers is that they never emit any byproducts or secondary pollutants such as ozone and ions.

The main instrument that makes the HEPA purifiers work so efficiently is the fan inside the filter. The fans aid in the trapping of large particles in the fold of the filters while the small particles and chemicals gets attached to the charcoal in the filter.

Some of the HEPA air-purifiers have fans that have a straight design where the air is drawn in from the back of the purifier and blown out through the front of the purifier. These units clean the air specifically and prove to be truly effective for bedrooms and sitting rooms. Others have unidirectional fans that pull the air from all sides of the machine and blow the filtered air out in all directions. These types of HEPA air-purifier are needed for purifying the air in the entire home. So whether it’s the larger particles or the smaller ones, the HEPA air-purifiers can clean the atmosphere completely.

Types of HEPA air-purifiers

The HEPA air-purifiers are hallmark of quality and dependability. The series of HEPA air-purifiers come in two basic configurations: standard with traditional electric motors and the PLUS systems featuring G.E. ECM Variable Speed, low energy motors. Either of these standard HEPA air-purifiers works with digital motor technology that is otherwise unavailable in any other whole-house filtration systems. The HEPA air-purifiers clean the atmosphere of the entire home effectively and instantly.

Benefits of HEPA air purifiers

With their effective technology, the HEPA air purifiers have well stowed away every other air-filters to a corner. They have adopted the same filtration effectiveness as required in hospital surgery rooms for cleaning rooms and in other applications where the removal of harmful respiratory elements are highly necessary.

Following are the benefits of HEPA air-purifiers:

-The compact design enables the purifiers to be easily installed in the homes.

-The patented by-pass approach allows for installation on any heating/cooling systems.

-The self-balancing air flow design adds no resistances to the flow of air.

-The three matched designed air filters like pre-filters, carbon air filters and HEPA air filters help in fast and instant filtering of air.

-These air filters are highly portable and can be installed anywhere in your home.

So how do you separate out the hype? This article will help you gain a basic understanding on what are the air purifiers out there in the marketplace and give you some tips to help you make an informed decision eventually.

There are three different kinds of air purifiers that work on different principles. They are ionic air purifiers, HEPA filter system and ultraviolet system air purifiers. Each has its pros and cons. The actual science behind how each type works is discussed more in detail at my website. Depending on your requirements and budgets, one of them will surely meet your needs.

Everyone has seen the infomercial for the Ionic Breeze. This well-known air purifier always has some special deal going. For example like “Get $100 off for a limited time.”, “Get a free mini-Ionic Breeze air purifier when you purchase one of their full-sized air purifiers.” Wow but is that really such good a deal?

In actual fact, many of these air purifier companies hope you will be tempted by their huge discount. Even with the discount, they are still making money. The more air purifiers they sell at the price, the more money goes into their pockets. So just be very careful!

Comparison Shopping
So you think that buying an air purifier directly from the company is always the best policy? Apparently not so. It will be good to do some price comparisons through many of today’s top shopping sites. You must understand that the shopping search engines make their commission on air purifiers regardless of the purchase price. Bottom line is that they just want sales. Thus, they are not biased toward what air purifier you buy so long as the product is bought through their site! So? Their only goal is to help find you the absolute best deal on your new air purifier so you will make a purchase on their site!

Word of Mouth
Yes, nothing is probably more important that reviews from people who have used the air purifiers before! You should always look into what other consumers or users have to say. There plenty of websites out there that provide consumers a chance to voice their experience and give ratings to the air purifiers. This help you quickly weed out the bad products and get you to focus on those air purifiers that are worth getting.
Warranty
In this day and age, most electrical products that we buy should come with a warranty. Thus you must take into account the warranty given when you are purchasing an air purifier. For example, “limited warranty” offers usually mean the company covers little if your air purifier breaks down. Always look for a solid air purifier warranty from a reputable company with a good customer relations department locally. You have to watch out for tricks used by companies like the “overnight it to us at your expense” clause. Sending air purifiers at overnight rates can often cost half of what air purifiers cost you in the first place. So remember to avoid a warranty with that requirement!

Look for Bargains
This comes after you have identified the exact model of air purifier that you have decided to buy. Go online and find a shopping search engine. Start by doing some comparison of air purifier prices. One excellent place to check out for great bargains are auction sites like Ebay. And you’ll find prices can range greatly. Thus do not just buy blindly without doing some bargain hunting.

Sometimes it will be hard to resist the many deals on air purifiers out there like “Free shipping.” “Buy any of our air purifiers and get a gift.” “No payments for a set amount of time.” The list goes on! Do not be swayed easily. Always spend some time to investigate first to help you choose what deal is best and works for you. Thus again, I hate to repeat this, but the best way to select the right one for your situation remains the one that your fifth grade teacher taught you. Do your own homework.

Some of different types of air purifiers are given below:

1. Ultraviolet air purifier: Ultraviolet air purifiers reduce toxic gas as well as remove volatile organic gases including harmful ones. In addition, it also kills germs and viruses present in air. It is also portable with easy maintenance especially with filters. Another benefit of this type of air purifier is that it is very quite and appears to be almost non-existence in terms of noise. Some UV air purifiers come with a filtering process that combines other types of air filters namely HEPA, ionization, and carbon. A motorized fan attached to this device is used to maintain a flow of air throughout the house.

2. Ionic air purifier: This type of purifier uses the effect of ionization to reduce contaminated particles and dust particles from air. Ionic air purifier ionizes contaminants as positively charged particles which are then attracted to a negatively charged plate to get rid of the pollutants or contaminants. For users with allergies, asthma problem use this type of air purifier. It also helps in getting rid of odors such as that of pets or cigarette smoking. Many ionic purifiers have adjustable power levels to allow user to adjust it according to room size. Generally, an ionic air purifier that weighs 10 pounds and has dimensions of 9 by 10.5 by 29 inches can cover an area of 500 square feet. Nowadays you can also find many ionic purifiers that don’t include a filter.

3. Edenpure air purifiers: This type of purifier not only eliminates contaminants from air but from surfaces as well. Many air contaminants are due to surfaces such as carpets, furniture, floor etc which causes respiratory problems. It also comes with a fan as well as a pre-filter mesh which instead of replacement requires washing with water.

4. Room air purifiers: One of the most commonly used, this type of purifier, designed for small sized room, gets rid of odors such as pet’s and smoking. This unit sucks in contaminated air, cleans it and sends filtered air back into the room. This unit is portable as well.

5. Ozone air purifiers: Strictly to be used in unoccupied rooms, this air purifier produces an oxidant ozone which get rid of many contaminants namely bacteria, germs, virus, formaldehyde, odors etc. Although an effective unit ozone has its own disadvantages and can be harmful to human body.

There are many benefits of using an air purifier:

1. It purifies air and removes contaminated particles making air healthier when you breathe-in.

2. It get rid of odors namely pet odor, cigarette smoking.

3. It comes in a variety of materials so you can easily find one that is within your budget.

4. Due to healthy and purified air you are ill less often.

quality of your indoor air, and not so much outdoor air, which is responsible for various health problems such as asthma, allergies, hay fever, etc. All

these can be taken care of with a proper air purification system for your home. But how do you choose one? Well, here are the factors to consider when

choosing an air purifier.

Criteria For Choosing Air Purifiers

1) Size of the area: The size of the room that you wish to purify is an important consideration when buying an air purifier. If you choose a purifier

that is too small, it will not effectively clean the indoor air, thus rendering itself useless. And if you choose one that is too big, you could be

wasting a lot of money on your power bill. Thus, before buying an air purifier, you should measure the area of the room (or whole house as the case may

be) and then buy an air cleaning system that has the ability to purify the area.

2) Your purification needs: Why do you need an air purifier? What do you wish to remove from your indoor air? These are two questions that need to be

answered before choosing an purifier. Let’s tackle them one by one.

• Most people want to buy an air purifier so that they can enhance their health through cleaner air. They wish to get rid of niggling allergies and

other health problems caused by bad indoor air. If that is the case, you need an air purifier for your whole house so that you can benefit from purer air

throughout your home. You should also ensure that the materials used in the air purification system as well as the filters are not ones that you are

allergic to and to which you can have a negative reaction. However, if you wish to purify selected areas in your home, it is best to go in for a portable

or a room air purifier, which can be used wherever you need it most.

• And now to the second question…what do you wish to eliminate from indoor air? Do you want to get rid of animal dander, or harmful germs and bacteria,

or disease causing particulates, or offensive odors and gases? If your primary need is to remove harmful particulates, then a HEPA air purifier is your

best bet as it effectively eliminates particles as small as 0.03 microns. To effectively remove germs and bacteria, you can choose an air purifier with a

UV system as these kill bacteria most effectively. However, in order to make your air as clean as possible, it is best to choose an air purifier that has

multiple filtration systems and not just one.

3) The CADR Rating: Clean Air Delivery Rate (CADR) is a rating that tells you how effective an air purifier is in eliminating dust mites, pollen

particles, and smoke from your indoor air. A higher CADR rating means the device is more effective and quicker at removing these harmful substances than

one with a lower CADR. Thus, you should select an air purifier with the best CADR rating.

4) Number of air changes per hour: This indicates the number of times a particular air purifier purifies the entire air within a given area in one hour.

Obviously, the higher the air changes per hour, the more efficient the purifier is, in not only purifying the air, but also maintaining its purity by

ridding the air of its impurities and pathogens rapidly and consistently. Thus, you need to choose one with as high air changing/hour rate as possible.

5) Maintenance and cleaning: Many people do not pay much attention to ease of cleaning the purifier when buying it and then get frustrated later on with

having to put in a lot of effort into its maintenance. While choosing an air purifier, you need to be aware of how regularly it needs to be serviced and

cleaned. How long can the filters be used before they need to be replaced? How expensive are the filters? Once you have the answers to these questions,

you can choose one which is easiest to clean and also not very expensive to maintain.

6) Noise Level: Some air purifiers make so much noise that they can literally wake up the dead! And since you want an purifier to enhance your health, it

is not going to happen if you choose a noisy one and lose sleep over it. Thus, check out the noise level of the air cleaner before making your purchase.

By following the above steps, you are sure to pick the ideal air purifier for your needs.

The modern air purifiers have gained such popularity in the consumer market that they have well mutated the use of air-cleaners. While the air-cleaners clean the air, the air-purifiers absorb dust, pollen, viruses, molds, tobacco smokes, dust mites and other industrial/household chemicals, thereby purifying the air completely. The people who get mostly benefited from air-purifiers are those that suffers from constant allergies, asthma and other respiratory ailments.

Today the air purifiers come in a package containing top-class elements that have increased the usage of air-purifiers to a great extent. The air-purifiers contain HEPA [High Efficiency Particulate Air] filters, ion generators, ozone generators, electrostatic filters, ultraviolet light and other methods that help the air-purifiers to get rid off both large and miniscule particles.

Air purifiers come in various shapes, sizes, and types. Out of these various types of air-purifiers, while some of the air-purifiers draw in air via a fan, cleaning the air and re-releasing it, most of the other air-purifiers work by actually spreading the purified air in the entire room.

Following are the various types of air-purifiers available in the market:

1) Room air-purifiers - room air purifiers have replaced the tabletop units in the 1990s as the leading brand of air-purifiers. These are portable, lightweight and flexible in use. So you can install them almost anywhere in your room.

2) Ion generators - these air-purifiers work by generating charged ions into the atmosphere. The ions get attached to the dirt and chemical-contents in the atmosphere causing them to get attracted to the floors of the houses and get deposited in the grounds. You can then wipe them, mop them or vacuum them away from floors.

3) Whole-house air-purifiers - these air-purifiers serve the purpose of cleaning and purifying the atmosphere of the entire home. These should be basically installed in a central heating, air-conditioning or HVAC systems. The purifier works with the help of a filter that is located in a return air-grille or plenum of the purifier. It’s the fan inside the air-purifier that basically takes in the air, moves it through the filter and releases the clean air out into the atmosphere.

4) HEPA Filtered air-purifiers - HEPA stands for High Efficiency Particulate Air and are made of charcoal. The filter in this air-purifier is placed upwind of a high-velocity fan on the unit, which actually drives the contaminants into the filter attracting tobacco smoke, dust mites and other pollutants. After the air is cleaned inside the purifier, the air is made to circulate in the entire home.

Now that you know the various types of air-purifiers that are available in the market, get the best air-purifier that will perfectly suit your needs and budget.

UV air purifiers use certain types of ultra violet light to neutralize and destroy microorganisms that live in our environment, such as bacteria and viruses, which can potentially be very harmful, particularly to young children or older people, or family members who have already been compromised by another illness. UV air purifiers are also effective in dealing with mold, and the tiny toxins that mold spores release.

Ultra violet air purifiers work by altering the DNA of these microorganisms, which results in their death. Don’t worry though – UV air purifiers won’t harm your DNA or that of your children in any way. These purifiers are completely safe for use in your home environment.

While the technology used in UV air purifiers is highly effective in killing bacteria and viruses, it cannot act as an air cleaning filter, and so by using this technology alone, dust and particles will remain present in the atmosphere in your home. For complete air purification, many manufacturers have combined ultra violet air purifiers with some other type of filter technology, such as HEPA, to ensure that the air you breathe is as safe and clean as possible.

UV air purifiers are highly effective at what they do, but are unable to perform the same functions as other air cleaning systems. So for the best of both worlds, choose a system for your home that offers both – an air cleaning filter and a uv air purifier.

UV air purifiers, a useful addition to your air purification arsenal.
