What Features Should a Great Air Purifier Have?

Features of Air Purifiers That You Need to Keep in Mind

According to professionals in the air purifier industry, the most important characteristic of a good air purifier is its HEPA filter. The reason is that HEPA is the most effective solution against small airborne particles and allergens. Even if there are other types of filters that use similar technologies to achieve great effectiveness, there aren’t many alternatives for eliminating particles that have a size of 0.1 microns or smaller.Tips to Test Indoor Air Quality

Maximum Air-Exchange Rate

The maximum air-exchange rate should be as high as possible. Every air filter allows the maximum quantity of air to go through it in one minute. Devices with a low maximum will allow less air to get through them, and cleaning the air will be slow.

Alert for filter change

There are filters that have an integrated counter and an alert system to notify the user when it is time for filter replacement. While many of these filters use a daily countdown, others monitor the filter’s current state.

Monitoring feature for air quality and sensor for dust

The quality of air can be automatically monitored, and air pollutants can be detected. With the information provided by the sensors, the device can automatically change the speed of air cleaning. Users then do not have to check or set the purifier, but there is a problem with this characteristic: less precise control of the level of noise and the consumption of energy. Despite this disadvantage, the feature is great in a space that is not occupied by people.

Multiple fan speeds

The purpose of having several speed settings for fans is better control of the airflow speed. The con of this characteristic is the higher noise level.

Larger capacity

The use of a large capacity is justified in spaces with more square footage than average, but a large capacity device can be more expensive. Cheaper options can be more practical, and they are sufficient for small spaces.

Lower ownership costs

The ownership costs can depend a lot on the type of filter that a device has. A permanent filter does not require replacement as it can be cleaned or vacuumed. There is no need to pay for a new filter during its functional lifespan. The majority of air purifiers have changeable filters that only need replacement every few years. The more often you have to replace the filters, the more you will have to pay for the ownership of the device in the long term. On the other hand, there are no reliable washable HEPA filters certified by professional organizations.

Low ozone level or no ozone

Even if professionals in the industry say that ozone is great for eliminating gases and odors, too much ozone can do more harm than good. If you select an electronic air purifier, you must pay attention to its ozone emissions. It is probably better to get a device that has low emissions or no ozone at all. Ozone generators that are commercialized as air cleaners are not a good choice.

  1. Hi SimonI agree that the ozone hole and climate caghne are very commonly thought of as the same problem. While there are interactions between the two, they are essentially separate problems. And the troubling part is that ozone depletion is essentially solved (or will be by continuing to adopt and enforce policies already in place), while climate caghne is far from solved – if people are confusing the issues, they may not understand the different messages they hear.I guess we should be overly clear in talking with the public, even to the point of not even mentioning the ozone hole if we’re talking about climate caghne. More primers on the basic science of climate caghne would definitely help. I think we also need to make clear that climate caghne is linked with energy use, and get people thinking about all the ways they use energy (and can reduce energy use).But how do you do it, and will people listen?Jason
