CADR, and MERV.
This value tells you the volume of air that can be filtered per hour of use. You'll want a higher ACH to ensure that all alergens and dust particles will be trapped.
While ACH tells you the number of cycles relative to your machine, CADR will tell you how much clean air will be put into your room per minute.
Consumer Reports states that a CADR above 350 is excellent, while one below 100 is poor.
MERV was developed by the American Society of Refergierating and Air-conditioning Engineers. It tells you how efficiently your air filter is working. A value of 10 is optimal.
Another way to ensure that your filter is working efficiently is to look for the Energy Star brand.
It's important to keep a good balance between noise levels and size. Often, a good quality air purifier, although expensive, will keep quiet.
Air purifiers come with a noise level rating in decibals (dB). The greater than dB, the noisier your air purifier is.
It's important to run your air cleaners at least 4 hours per day. Air cleaners take some time to reach a "cleaning equilibrium", so it's important to keep your cleaners at work.
Some filters that work by placing a charge on the particles in the air before pushing them back out may cause ozone gas. They might smell "fresher," but can be unhealthy.
Luckily, many of the products on the market today readily convert the ozone gas back to oxygen before pushing it back out. It's good to make sure you check with each product to ensure there is no ozone being produced.
Windows open mean fresh air...right? Interestingly, when using air filters, this doesn't apply. It's important to keep windows closed, as air purifiers function the best when recirculating the same air over and over again.
You'll want to place your filters nearest to where you most frequent, so that you may breathe in the freshest air. If you're often on your computer in a room, then place the filter near there. Then you can move it next to your bed while you sleep.
Air purifiers can make the air in your room cleaner, but that doesn't mean your household will be free of cat fur. In order to minimize the amount of time you spend performing chores, we recommend selecting from our guide of recommended Roomba robot vacuums. In addition to automating keeping the air in your home clean, Roombas will help you rid of cat hairs from your carpets.
If Roombas are not your thing, you could always select a pet vacuum cleaner that is built to pull cat hair out of your carpets.
Unfortunately, having an air purifier isn't an excuse to stop cleaning. Remember that air purifiers are there to clean the dander and dust out of the air, but those particles can still be attached to the floor or walls.
Here is a list of items that were curated through the internet. It's best to first measure how large the room you want to place your air purifier in, then look up which product is built for that size.
If you're on a budget and want and air purification system that helps fight dust, cat dander and allergies, try the GermGuardian 3-in-1. In addition to a HEPA filter, the GermGuardian fights germs and bacteria with its UV light technology. Additionally, its replacement filters are relatively cheap, keeping your budget steady for the long run.
If you have a little more to spend to get a much higher return than the GemGuardian, try the Alen T500 Tower Air Purifier. This is a powerful, quiet, compact, portable tower with up to 63% more efficiency than GemGuardian, and has the ability to clear out over 3 times the space!
The Rabbit Air MinusA2 covers a large amount of space (up to 700 sq. ft), is ultra quiet and HEPA qualified. Select from the particular from a list of subtypes including Germ Defense, Odor Remover, Pet Allergy or Toxin Absorber. Its six-stage filtration system traps in dust, pet dander, pollen and charges particles in the air so that they may stick together and be removed more easily. Additionally, as with all Alen brands, it comes with a 5-year warranty, keeping your mind at ease in case of breakdowns!
The Alen BreatheSmart is as elegant in looks as in its technology. This high-end model uses its SmartSensor Technology to detect airborne allergens and pollutants, and automatically turns itself up or down accordingly.
Additionally, the Alen Breathemart offers four different types of filters, interchangeable according to your purpose. There is a HEPA-Pure (for dust and allergens), the HEPA-Silver (for bacteria and germs), HEPA-OdorCell (for smoke and heavy odors, included in box) and HEPA-FreshPlus (for chemicals and VOC's).
Looking for a heavy-duty air purifier that can cover a large living room? Try AirMega 400S, which has a coverage of 1,560 ft2. This is ideal if you want to keep a large living space (such as your main living room) clean for guests, who may be allergic to cats.
