Room Air Purifier - Why Not A
Whole House Air Cleaner?
If you have just determined that you need a room air purifier for a variety of reasons, you may be wondering why not just install a whole house air cleaner? However, if you need a room air purifier for one specific room, then why spend the money for a whole house air cleaner. There are many reasons why you should not and there may be reasons why you may want to. However, typically there is no need try to clean the air in the whole house when you only have issues in a small part of your home.
Whole house air cleaners only clean the air as it passes by the air cleaner that is mounted in the central air system’s duct work. The problem can be that the air just gets contaminated all over again as it travels through the duct work to get to the one room that needs purifying. This is a complete waste of resources and it is ineffective. This also does not take into consideration that the central air system requires the air to be returned back to the central air system. If there are closed doors or the room that needs to be purified is a long distance from the central air system, the air will not be exchanged efficiently.
One way that might help a central system air purifier is to have all the duct work cleaned. This is a costly and difficult to achieve project. This is because not all the toxins that have built up in the duct work can be removed. Basically, your best bet for a whole house air purifier is to put it in a brand new installation. Also, the installation design has taken into consideration of how to purify the air in a room that is furthest from the central air system.
The easiest and most economical approach is to purchase an air purifier that is designed for one room use and placed in the targeted room. Even if the door is closed, the room air purifier is effective, because its main focus is the room. Typical room air purifiers clean an area around 500 square feet.
The room air purifier is much more efficient in design and cost when a specific room needs tobe cleaned. You can buy an effective room purifier for less than $300 and get the results you want. Or you can pay for a whole house air purifier that may cost in the thousands depending on difficulty of installation and any additional electrical needs for the whole house air purifier.
For example, if your home only has 100 AMP service and you want to add a whole house air purifier. The contractor will probably say you will need to upgrade to a 200 AMP service. You can now add another $1000 on the bill. You could have three to four very effective room air purifiers in your home just for the cost of the electrical upgrade alone.
The feasibility of a whole house air cleaner accomplishing the purification of one particular room in your home is unrealistic. Typical design issues and costs for a whole house air purifiers lead to the obvious choice of a one room air purifier for most people’s requirements.
