You are worried about air pollution because of all of the cars on the road and the factories pouring tons of toxic gases into the atmosphere?
We are too. But how about this:
The air quality inside your own home can be many times worse than that of the outside air.
The obvious solution is to purchase an air filtering system. But there are a number of factors to consider in choosing a home air purifier so we’re going to discuss these and give you some tips to help get you pointed in the right direction.
Area of Coverage and Air Changes per Hour
The area of coverage is simply the size of the room that your future air purifier is going to be useful for.
This is an important consideration and you would have to find a fine balance here. Because it your air purifier is too small it will not do a good job of purifying the air.
On the other hand, if your air purifier is too big you may end up wasting a lot of money on energy costs.
When deciding which size air purifier to purchase, you would have to consider the ACH factor, which stands for “air changes per hour”. This is the number of times that an air purifier is able to process all of the air in a given size room in an one-hour.
A common ACH recommendation is approximately 4 to 6. For example, Honeywell 17000 S has a pretty high ACH number of 6.
This means that your air cleaner should be able to cycle through all of the air in a room between 4 and 6 times per hour.
Now, it is easy to find this number on the manufacturer’s side. A great number of air purifiers will tell you exactly how many cubic feet of air they are capable of processing.
However, you will need to figure out how many cubic feet of air you have in the room that you will be putting the air purifier in.
To do this, simply multiply the length of your room by the width and then multiply the number you have gotten by the height. This simple operation will give you the number of cubic feet in your room.
One of the most important factors to consider when you chose a home air purification system is the cost of replacement filters.
Of course, you also need to check how often they will need to be changed.
And how often the filters will need to be changed depends on how much you are going to use your air purifier.
The manufacturer of a particular machine will often give you some guidelines. Some filters will need to be replaced once per year and others will have to be replaced two or three times each year, even more often.
The replacement cost of a HEPA air filter can be anywhere from $20 to \$40 all the way up to well over $100. It depends on the type of machine.
As a rele, the more expensive and more effective purifiers have also more expensive filters.
If you will have to spend over $100 twice per year, this would be good information to have before purchasing an air purifier and it is important to research this before you make a decision.
One good example is IQAir HealthPro. Their HEPA filter lasts for up to 4 years.
This is another hidden cost of using an air purifier.
Many air purifiers available today are very energy efficient.
Keep in mind that you will likely run your air purifier 24 hours per day.
So it’s a good idea to do a little research and figure out how much energy an air purifier uses before making a purchase.
Air purifiers might use anywhere from 50 watts on lower settings to 200 watts on higher settings but the numbers will be different from one machine to another. By all means, energy consumption is something you should take into serious consideration. For example, Germ Guardian is energy star compliant and it won’t increase your electricity bills too much.
The amount of noise a machine makes is something that you might want to look into as well.
Some people don’t mind a loud machine because they will have the machine running when they are not home or when they are in another room and then they will simply run the machine on a lower setting when sleeping or watching television.
However, a noisy machine is a dealbreaker for a lot of people. People with bad allergies might need to have an air purifier running on at least a medium setting in the room with them while they are sleeping at night so noise is a very important issue for a lot of people.
The noise level of an air purifier will usually be stated on the unit’s packaging or can be found by doing a quick search for the make and model number online. The sound level is measured in decibels and a quick search will tell you how many decibels a machine produces on its various settings.
Safety is another important factor to consider in choosing a home air purifier or any other product for that matter. Most air purifiers are perfectly safe.
HEPA filters and activated charcoal filters do not introduce anything into your environment and are therefore perfectly safe.
Ozone generators that are used to remove odors and reduce the amount of mold or microbes in a room can be potentially dangerous. Ozone is irritating to the respiratory system and is particularly dangerous for the very young, the very old and anyone with chronic lung diseases.
Ionizing air purifiers also produce small amounts of ozone and for most people it is not an issue but for highly sensitive people even this small amount of ozone can be irritating.
As you can see there are a lot of factors to consider in choosing a home air purifier. Purchasing an air purifier can be expensive but what is even more important is your health and because many people purchase air purifiers for better health and to help with allergy symptoms it is important to do your due diligence and find a machine that will be beneficial to both your health and your budget.
