If you decide to look around a few of these products and do some research, then I assure you that it’s not going to be an easy task unless you spend some quality time in reading about air purifiers. I don’t intend to scare you, but the reality is that there are a lot of technical terms and massive scientific jargon associated with these products.

Do you want to buy a home air purifier but don’t know which one is the best for you ?
Are you overwhelmed by the choice out there ?

Don’t worry!! You are not alone.

Today’s market is literally swarmed with thousands of air cleaners and almost all of them promise to deliver the best quality air. But how much belief do you have in their claims? To start with, you have different types of home air purifier to consider and compare, such as the HEPA versus Ionic air purifiers. Then there are different brands, including Honeywell and BlueAir.

Worse, many online and offline vendors only provide product specification which, in our opinion, is totally meaningless because unless you understand the significance of each feature, you cannot make a great purchase.

Therefore, it is not surprising that many people end up buying the wrong ones. Considering the high cost of a home air cleaner and the potential health hazard you can be exposed to with the wrong products, this is the mistake you do not want to make.

How to Choose Air Purifiers: Buying Guide

I’m the kind of a person who likes to do a bit of research and learn about the products before making a purchase decision. I assume there would be many others like me who would love to have a dose of information. So if you are one among them then go ahead and read along this article.

Before making any decision, I suggest you  read my purchase guide for air cleaners which will tell you precisely about all the necessary functionalities and important features that you should be looking at an air purifier. The ultimate aim of this guide is to help you make an informed decision.

I’ve also written quite a few feature specific articles and other informational stuff to make things easier. So I urge you not to be in a hurry and read through the information before selecting the right product that fits in with your requirements.

Also, I have compiled a list of tips for first time buyers that would definitely come handy for an inexperienced buyer.

What does CADR mean

The term ‘Clean Air Delivery Rate’ was actually coined by American Home Appliance Manufacturers (AHAM). In simple terms, CADR is the measure how effectively an air filter can remove the contaminants and pollutants present in the room and deliver crispy clean air. CADR ratings for Smoke, Dust and Pollen are individually represented.

This is one term that you will be reading a lot about because it is an industry standard. You can read more on this topic here.

Now that you have a basic understanding of CADR, let’s look at some other important details like Air Flow Rate, Purifier sizing and positioning.

Rate of Air Change and Performance

Air Purifiers use a fan to pull in the air which is then forced to pass through the filters. After filtration, the pure air is then pumped out back into the room. The speed of these fans is adjustable. So air flow is directly dependent on the speed of the fan and the number of filters.

Air Change Rate‘ in short is the number of times the purifier can clean the air present within the room. So this has a lot to do with the size of the room and also the capacity of the purifier itself.

If the air change rate is too low then you should probably rethink your choice of air purifier because the indoor air gets stagnant and thus it may negatively affect your health.

Sizing

Having a proper idea about the size of the room in which the air purifier is going to be placed will definitely help you in choosing the right product. Many people end up buying a purifier that this just too small and has a much lower capacity to purify the contaminated air in their house. Check out my article on choosing the perfect one that fits well for your room size.

Placement

This is one of the top priorities that you need to answer after you purchase the air cleaner. For the purifier to work perfectly it has to be placed in such a location where it is not obstructed and will be able to pull in the air much easily. There are several other things that you need to keep in mind before you decide on the placement.

Types of Filters Used

Filters are probably the heart and brain of an air purifier. These filters do all the grunt work of cleaning up the air and arresting all the impurities and contaminants that you don’t want to breathe in. Right from the beginning, there have been many innovations and developments in this field, with each one intended to improve the quality of air that is being delivered. Below I have mentioned a few of these filters along with links for each one.

HEPA Filters

A majority of the air purifiers which you’ll be seeing would have these HEPA filters on them. These filters are highly effective and are able to purify the air up to 99.9%. These, when used in combination with other prefilters (like Charcoal filters) will significantly increase the filtering capacity.

Activated Carbon (Charcoal) Filters

These filters help them capture in large sized contaminants like pet hair, dust and other particles of such proportions. When used individually these filters are less effective in cleaning the air. So it is probably best to choose an air purifier which uses these for pre-filtering purposes.

Ionizers, Ultra Violet, and Electrostatic Filters

These filters use a different filtration technology to purify the air and are nowadays used along with HEPA filters. I have made a separate article for each these. Here you will be able to understand the functioning of air cleaners which use these filtration technologies.

What Is An Acceptable Indoor Air Quality ?

How do you know that the indoor air quality of your home is acceptable and up to standard ?

These are the questions many people ask once they realize that air indoors can be as polluted as outside air. In fact, statistics from the Environmental Protection Agency (EPA) shows that the air inside our homes is actually 2-5 times more polluted than outside air.

This article will help you to answer these questions without having to pay for pricey home air quality inspections.

What is an Acceptable Indoor Air Quality for Your Home ?

There are all sorts of indoor air quality standards which an expert individual can measure. However, if you don’t want to invest on an air quality inspections, then use the checklist below to gauge how clean the air within your home is.

Basically, the air inside your house is acceptable if:

1. Your house has good air changes per hour.

In order for a home to have an acceptable indoor air quality, it should have a good ventilation system to ensure air changes. Decent air changes will dilute indoor pollutants considerably and increase air quality. In order to achieve this, not only should a house be aired frequently by opening the doors and windows. But also, it should have a good forced air system for air conditioning and heating as well as a good exhaust fan for windowless areas, such as the bathroom.

How good is good though ?

Acceptable indoor air quality standards, including air changes, differs from building to building and room to room. For instance, at the extreme, commercial kitchens should have 20-30 air changes per hour, whereas warehouses only need 1-2 air changes per hour. Air changes requirement for a house might be closer to that of a classroom, which is 3-4 air changes per hour, provided the members of family are healthy. The requirement of the air changes increases if you have a family member who has medical problems and is sensitive to the quality of indoor air.

But how do you measure the air changes ?

In a typical airtight house in the US, where houses are continuously cooled down in summer months and heated up in winter and with a minimal air leakage, air change depends a lot on the HVAC system. An HVAC contractor can be called to judge the quality of your HVAC system and to see whether it provides good air changes.

But, if you only want to have a rough idea how clean your home indoor air is, look at the warning signs below which indicate that your home has a poor air change system :

  • mold
  • stalled or smelly indoor air.
  • condensation along the window.
  • dirty central heating or cooling equipment
2. No one has illnesses which can be attributed to poor air quality.

When air quality of a home deteriorates, the most sensitive member of its inhabitant is usually the first who takes the brunt. These are adults or children who can’t stand living in polluted homes and usually have allergy, asthma, other types of lung diseases or multiple chemical sensitivities which make them react to poor air.

If one member of the family starts sneezing, coughing, having headache, and so forth, after moving to a new home, or after having a new home refurbished, it might be a sign that the air quality is off.

3. The absence of a lifestyle which can make the home air quality worse.

Your lifestyle and the lifestyle of other people living with you can also be used as a gauge of your home’ air quality. A house full of smokers or pets is very likely to have a poorer air quality in general. Similarly, frequent use of strong cleaning agent and pesticides in a particular house means that the house may have, in some degree, accumulation of toxic fume.

In addition, if your house has just been refurbished, or if you just move into a new home altogether, you should be aware that the off-gassing from painting, new carpet, and so forth, will be present for a period of time.

If you are worried that you don’t have an acceptable indoor air quality in your home because of your lifestyle, then it is a good idea to invest in a good quality air purifier.

4. Home is not built in the middle of polluted environment.

Homes built in the industrial area surrounded by chemical plants have a higher chance of having an indoor air quality problems than the ones built in a place where the outdoor air is considerably cleaner.

5. Indoor air pollutant measurement doesn’t show an alarming presence of pollutants.

Another way to gauge whether the air inside your home meets the optimal air quality standards is by doing an indoor air quality assessment. EPA recommends that you measure at least the level of radon, a dangerous colorless, odorless, radioactive gas in your home by using a test kit. A more comprehensive test on other indoor air pollutants or even an indoor air quality inspection may be performed if you suspect that the quality of your house air affects the health of the inhabitants.

Additionally, if you’re moving to a new home, you may want to couple the general house inspection with an air quality inspection to prevent the problems down the road, especially if one of the members of the family has a medical issue which requires a clean air.

You may want to read more about how this affects your health adversely by following this link.

Finally, if the air quality measurement shows no alarming presence of pollutants, you can be rest assured that your home has an acceptable indoor air quality.

Safety Concerns On Air Purifier Usage

Are air purifiers safe ?

This is a good question to ask prior to buying any purifiers. After all, everybody wants air purifiers to improve their lives, not making them worse.

The short answer to the question whether air cleaners are safe is: yes. Most air cleaners are safe for general use. However, some of them are not that safe.

So which air cleaners are safe then ?

In order to answer these questions, we have to first look at the air purification systems used by home air purifiers because the safety of an air cleaner is closely linked to the air purification system it uses to purify the air.

Among the air purifiers, there are two types which are questionable in terms of safety. They are: ozone air purifiers and ionic air purifiers.

Let us explain one by one.

Why Aren’t Ozone Air Purifiers Safe ?

One of the technologies which can be employed by air purifiers to clean air is ozone, a highly reactive oxidant. Ozone air purifiers are designed to emit a high-quantity of ozone so that the ozone can react chemically with airborne particles, hence converting those particles into supposedly harmless chemicals.

Since ozone can irritate soft tissues, including eyes and the respiratory tracts, the use of such high concentration of ozone is not safe. In fact, such ozone generators are originally only used for industrial purpose and in places where nobody is going to be present for a while, for instance, for cleaning up empty areas or houses struck by natural disasters.

Unfortunately, some of the ozone air purifiers have made it to the home air purifier market. The manufacturers of course claim that they are safe since most of them are within EPA (Environmental Protection Agency) ozone limit, which is 0.05 ppm. However, EPA found that when used within EPA’s ozone limit, this type of air purifier is not effective enough.

On top of that, even when used within EPA’s ozone limit, that level of ozone still causes irritation for people who are particularly sensitive to chemicals as well as people with respiratory diseases. Moreover, EPA also found that often, customers put the air purifier in a room smaller than the recommended size, hence the ozone level in that room ends up being higher than what is deemed safe by the EPA.

Therefore, if you want a safe air purifier, it is better to avoid ozone air purifiers. Not only you should avoid them because of the safety issue, but also on the effectivity grounds.

Are Ionic Air Purifiers Safe?

Another type of air purifiers use ionizer to clean air up. These air purifiers are called ionic air purifiers. Ionic air purifiers clean air by emitting charged ions (usually negatively-charged ions). These ions are expected to bind to airborne particles, hence dragging them down to the floor. This way, the airborne particles are no longer airborne and can be vacuumed away. Some ionic air purifiers, called electrostatic air purifiers, suck ionized airborne particles to the machine and stick them to a pair of electrostatic plates, hence removing them from the room.

The problem with this air purification technologies is that it can emit ozone as a by-product. This is because during the process of ionization, a high voltage has to be applied within the machine, and this process releases ozone by product. The amount of ozone emitted is small and most are within EPA threshold. However, people who have lung diseases including asthma patients should avoid such purifier since their lungs are already sensitive and easily irritated. In addition, people who are immunity levels are low and have chemical sensitivity should also choose other non-ozone emitting air purifiers. Healthy people generally can tolerate ozone, but if you have a choice, we suggest you to avoid these altogether because there are many other good quality air purifiers which are completely safe.

Having said that, it is important to mention that there are some ionic air purifiers which are safe. These air purifiers do not emit ozone or emit negligible (below background) amount of ozone, for instance: the high quality Blueair ionic air purifiers are completely safe and effective.

Are HEPA air purifiers safe ?

HEPA air purifiers are air purifiers which use high efficiency (HEPA) filters to filter out airborne particles. Filtration is basically the oldest way you can clean something up. It works purely by mechanical means.

HEPA air purifiers are safe. Effectiveness varies, depending on the brand. The only drawback is that usually these air purifiers are noisier and you need to replace the filters from time to time. This is in contrast to electronic air purifiers such as ionic and ozone air purifiers. They, in general, are quieter and don’t have anything to replace. In case with electrostatic air purifiers, the only thing you have to be aware of is that you should wash the electrostatic plates regularly to maintain the effectiveness of the machine.

Nevertheless, we recommend HEPA air purifiers highly because of the safety issue.

More Note on Air Purifier Safety For People With Chemical Sensitivity and Asthma.

For most people, as long as an air purifier does not emit ozone, it’s safe to buy. People with multiple chemical sensitivity (MCS), and lung-disease sufferers are however a different bunch. If you had such condition, then it’s better to buy a safe air purifier which does not emit any kinds of gas. Ozone-emitting air purifiers should definitely be avoided. It is also better to avoid air purifiers which emit gases from materials used for air purifier housing or casing. These gases are usually well-tolerated by normal people, but can irritate people with multiple chemical sensitivity or gas sensitivity.

So where do you find such safe air purifiers ?

Here is some rules of thumb:

  • Prefer air purifiers with metal instead of plastic casing.
  • Buy premium air purifiers . Not only are they highly effective to alleviate symptoms for people with multiple chemical sensitivity and sensitive respiratory track, but they are also safe. They do not emit ozone, have metal casing and use non-toxic paint. In addition, they often have label or little booklet saying: ‘no ozone’ and ‘no off-gassing’ to help customers to identify those safe air purifiers. In addition, if you want to shop for them online, many online allergy stores which carry safe air purifiers put the no-ozone and no off-gassing features in their product description. So it should not be too difficult to identify them.

Final thoughts

I have done my best to present this website and make it as information as possible. In the past, I myself was a victim of various ailments and was prone to allergy attacks. So, in my quest to fight these diseases I came across air purifiers. Much sooner I realized that not all these purifiers are as good as they say. There is a lot of misinformation floating around on the Internet.

I have spent many hours trying to figure out which purifiers work best for me and during this process I have gained a lot of knowledge which helped me make a good buy. So I thought that there might be many other people just like me who are equally if not more confused. And as a result, I have decided to combine my reviews. I have provided not only good but also my honest reviews.

We will be happy to hear your thoughts
