How to choose the best air purifier for pets

Okay, let me stop you here. How will you even know which air purifier is the best in the market? Is there any right-hand rule here? The answer is no. The best pet air purifier is the one that fits according to your requirements.

Still, you should consider the following before choosing an air purifier for pets.

Step 1: Consider size

There is no such thing as lack of breathing space when it comes to air purifiers. The main job of the air purifier is to clean the air in your room. If your room is too large or your pet air purifier is too small, it might not prove as effective.

Step 2: Pay attention to CADR ratings

The quality of any air purifier is measured by its Clean Air Delivery Rate, or simply CADR, rating. CADR represents how quickly an air purifier can clean the room for a specific room size.

Let me give an example: An air purifier with 300 CADR will clean the 250 sq. ft. room faster than the one with 200 CADR. In simpler words, if you have a large room size, you should choose a higher CADR rating.

Step 3: Consider the cost of maintenance

Almost all pet air purifiers are assembled with air filters, such as the HEPA filter. These filters need to be replaced every six months. If you live in a dusty area, like near to a construction site, you may even consider replacing it even before that.

Step 4: Think about automatic monitoring

Not everything can be seen with an eye or a pet camera. These days, many modern air purifiers are equipped with air monitoring infrared sensors.

These sensors automatically adjust the CADR and reduce stress on the purifier.

Some of these sensors connect to your smartphones and help you track air quality in your room. It may not seem much, but it is definitely something to consider.

Step 5: Consider noise level

Noise can be extremely intimidating for some people. 80% of our readers are using cat fountains, automatic litter boxes, or automatic wet food feeders.

Just imagine what will happen if you add up all these noises?

And an air cleaner making a humming sound right next to your nightstand can be very irritating. Some people even complain about insomnia.

In such cases, it is important to consider noise level in your pet air purifier. Although the noise from the air purifier is caused by the flow of air, it can be a little too much. A good air purifier would exhibit 30-32 dB noise which is a little above whisper (28dB).

Step 6: Research the manufacturer’s reputation

If I told you that you can experience the air purifier even before buying it, would you believe me?

Yes, I am serious. Manufacturer’s reputation is a crucial identifier to assess the quality of the product. Go through the review section of Amazon and read what people have to say about the manufacturer. Ideally, the best air purifier for pets must be able to gain trust of its users.

Step 7: Warranty

You know what? No one, not even the manufacturer himself, can guarantee that the product won’t break after a month.

A company offering warranty on the product can be deal breaker for some. And we strongly advise you to consider this before buying the best pet air purifier for your home.

Types of pet air purifiers

We have mentioned HEPA filtered pet air purifiers many times already, but is it our only option? Of course not!

So, what are exactly the types of pet air purifiers that we can use?

1. Filtered

There are two very common types of filtered air purifiers. One is the famous HEPA filter and the other one is the Carbon filter. 

HEPA stands for High-Efficiency Particulate Air and, like its name, is super-efficient. They are capable of absorbing 99.7% of particles above the size of 0.3 microns. In simpler words, if your cat is shedding hair, HEPA filters are the best.

2. Ionizers

Ionizers typically use a scientific method to clean air. The purifier discharges negative ions into air that react with air toxins. As a result, these particles become heavy and fall on the floor.

From there, it’s just a simple task for you to sweep the floor. It’s not the best option considering you would have a pet running around wild in your home. But if you don’t have any other options, this one is the right thing to choose.

3. Ozone Purifiers

Similarly, ozone purifiers are specifically used to remove odor in your home. They work like ionizers, but are dedicated for the removal of odor from the room.

So, let me ask again? Does your pet produce a lot of bad smell? If yes, then ozone purifiers are the best pet air purifiers for odor. And you should consider one for your home right now!

4. UV Purifiers

Are you sick and tired of worrying about the germs your pet may carry in your home? After all, we are horrified by the Coronavirus pandemic and can’t risk our health.

So, in such circumstances, UV Air Purifiers are the best thing to go for. They are designed to remove the bacteria and viruses from your home using UV radiations. These radiations destroy these microorganisms and stop these pathogens from multiplying.

Vital features of high-quality purifiers for pets

Now that we know about our option in types, the job of searching for the best air purifier for pets becomes easier. But wait! We still have plenty of features to look out for. Let’s discuss each one of them in detail.

1. HEPA Filters

HEPA filters are a must-have when it comes to pet air purifiers. Although it may not kill any germs, HEPA filters are vital against toxins.

An air purifier with 1 micron HEPA filter will do most of the job for domestic pets such as dogs and cats. If you want to pet birds, you may consider 0.5 micron filters.

2. Carbon Filters

As I mentioned earlier, carbon filters are responsible for room odor. So, if you are looking to kill the odor your pet is causing, you should go look for carbon filters in your air purifiers.

3. Purification Capacity

CADR is a really important aspect to consider when you buy a pet air purifier. Not only does it specify how quickly a room will be purified, it also indicates how big a room it can purify.

So the best air purifier for you and your pet would be the one that fits your room requirements.

Purified air will prevent your cat’s skin from drying out and will help you to get rid of dandruff in your cat.

4. Anti-Bacterial Coating

Wouldn’t it be great if your air purifier could clean the air around your pet AND kill the pathogens they carry? Yes, it would!

These days, air purifiers come with an extra layer of anti-bacterial coating. This, in theory, kills all pathogens in the air. The effectiveness of an anti-bacterial coating is underrated. In fact, lack of such coatings is definitely a deal breaker.

5. Air Quality Sensors

This is a digital age and every one of us wants to remain informed. So, so do our gadgets! An air quality sensor installed in your pet air purifier can help you track the air quality of your room.

This may seem like an unimportant feature, but it’s really not. And if you listen to me, you should definitely look for it when buying the best pet air purifier.

6. Child Lock

Having an unattended child running around a sensitive tech gadget is always a bad idea. Make sure the air purifier you choose has a child lock programmed inside it.
