However, this will depend on several things, like if you want it to do several tasks – like Dorm Room, or Cold and Flu symptoms.

Sometimes cats have issue with nose blockage or congestion, sometimes more than other pets. The chances of respiratory diseases can be high.

Sources like viruses, bacteria, fungi, and protozoa cause these kinds of infections affect your loving cat’s wellbeing.

These microscopic organisms that cause cat congestion aren't deadly in fully grown cats, but your cats won't eat if they can’t smell their food, so they would starve if they get a blocked nose or congestion.

How effective the cat vaccines are?

Nowadays, vaccines are available that reduces the chance of a cat’s respiratory problem or a common cold but they have not entirely eliminated the contagious pathogens and your cat may still have these issues.

Your home cares not just to make your cat more comfortable but decides whether your cat may recover or not.

Home remedy for your cat cold problem

Cats can also get colds like humans, and their symptoms are very similar to ours. They get a runny nose, cough, and sneeze, which is why keeping their air moist with a humidifier can be very beneficial.

A humidifier is an extraordinary solution that battles the dry air's terrible reactions. It will relieve their nasal passages, helping them breathe correctly and alleviating other cold symptoms they may be experiencing.

Which humidifier is best?

A great number of people are searching for books or various types of support that can help their cats to get off these unfortunate respiratory problems and to actually pass quality time with their lovely cat. If you visit your neighborhood pet shop or search the internet, you will find lots of different devices and articles that they have.

It can be totally overwhelming things from books to actual devices that make really extreme promises like curing your cat’s congestion right away or understanding your cat problems better. How would you know who you can trust and what are really evidence-based articles that help you decide which makes significant long term improvement of your cat?

Yet, Are any of these humidifiers even dependent on cat health research and which one of these humidifiers has really been able to show valuable improvements to various breed cats?

Furthermore, this is important to consider that the humidifiers that you're purchasing could simply be harmful to your cat rather than help them. You should be careful to choose from. That’s why you need evidence-based guidance, backed by cat health science that can assist you to settle on choices and get past difficult situations with your own knowledge and bring you back the lovely cat into your life again.

Let’s walk step by step.

Consider the size of your room

Above all else, you should measure the area or volume of the room where your humidifier is to be set up. If the doors to different rooms are open, then air will also circulate through them and the area or volume of those rooms should be included in the measure as well.

Humidifier producers always specify the suggested room size for their particular humidifier model. You should buy it according to your room size. The room area is calculated by multiplying room’s length, width and volume are by multiplying the room’s length, width, and the ceiling height.

Select a humidifier which at least recommended for your room area or volume. For example, if your room has an area of 30 m2 you have to pick a humidifier that is suggested for 30 m2 or more.

Why does water hardness so significant while picking a humidifier?

Water hardness is determined by the amount of mineral dissolved in your water specially calcium and magnesium. The higher the amount of those minerals, the harder the water is. A specific humidification system is to be selected as per the hardness of your water because different types of humidifiers respond better or not all that well to a high limescale content.

If you don't have any idea about the hardness of your house water, you can ask your water provider or you can easily find that data on the water provider's site.

There are 4 unique sorts of humidifiers: evaporator, ultrasonic nebulizer, vaporiser, and air washer.

For Soft water (0°–4°dH) and Medium-hard water (5°–13°dH) all types of humidifiers can perform fairly. In case If you have hard water (14°dH<), we suggest that you use evaporators or air washers. If you choose air washers, the anti-calcium cartridge has to change on a regular basis.

Vaporisers and ultrasonic humidifiers don't perform well with water which has high limescale content because a great deal of the limescale will be stored on the heating plate.

If your home system has hard water but you would like an ultrasonic humidifier nevertheless, we suggest that you mix the tap water with distilled water in a 50:50 ratio to reduce the water hardness.

Which humidifier is quiet enough for a cat?

Cats can hear sounds from 55 to 79,000 Hz. Ultrasonic humidifiers work at a frequency past what people or cats can hear – 1.7 million hertz which is 20 times above the cat’s hearing limit.

However, there's a little fan inside the humidifier rotating at a much lower speed and this sound can be sufficient to trigger the cat’s interest. The quietest types are evaporators and air washers. The bottom line is that an ultrasonic humidifier isn't suggested for a very young kitten or extremely curious cat that may push it off the table.

Then again, ultrasonic cat repellent supported humidifiers can keep away your cat and you may find such soft background noises quite calming. Considering noise, ultrasonic humidifiers are quite suitable if it is supported by ultrasonic cat repellent.

Power Consumption of humidifier

If your home air is very dry then you will have to keep your humidifier turned on all the time and it would cost you a lot of electricity bill. However, you can control the power consumption depending on the fact that whether your humidifier has a hygrostat or not.

Whenever your room humidity reached the target level, hygrostat will turn off the humidifier automatically saving lots of your bill. Considering the electricity bill, it’s safe to say that humidifier associated with hygrometer is most preferable.

 Are essential oils safe for cats?

Essential oils may help you with relaxation and de-stress but they probably won't work the same for your cat. Truth be told, essential oils may be irritating or hurtful to the cats. Cats have a sharp feeling of smell – which is about 14 times more than a normal human.

A smell that is barely noticeable by the human may be overwhelmingly rough to cats. Furthermore, essential oil elements like Monoterpene hydrocarbon and Phenols, can be poisonous to the cats. To put it plainly, essential oils can be poisonous for your cat and should not be used in humidifiers!

Cold mist humidifier or hot mist humidifier for a cat?

In case you are going to utilize a humidifier for your cat, a cool-mist humidifier is the best reported by the American Society for the Prevention of Cruelty to Animals (ASPCA). What’s more, is that they are more secure to use.

Just run the humidifier in the room where your cat normally hangs out and let them receive the benefits. You will see a huge positive change in their skin and coat within a couple of days.

Does humidifier size matter?

The simplest answer to that question is “Yes”. You might need to place the humidifier at different places before you find the right spot for you and your cat. A small size humidifier would help you a lot with that.

What about programmable and sturdy humidifier?

Who doesn’t want the flexibility to run a device? A programmable humidifier will just give you that. If you need to leave your cat alone at home, programmable humidifiers are the best choice. You can be able to control the running time, amount of humidification and so much more.

Cat is a fun-loving and playful animal. They will most likely have interaction with your humidifier. You have to make sure that your humidifier is quite sturdy too.


Maintenance is another key factor in choosing a humidifier. For hard water supply in your house, it would be more costly than soft water supply. Water minerals like calcium and magnesium are likely to be stored on the heating plate and will need to clean that more often.

So choosing a humidifier that is easy to clean is also bears great importance. For example, air washers have an easy cleaning process, cleaning it would be a child’s play. If you want ultrasonic or evaporators then you should also include the price of anti-calc cartridge or filter as you will need to change them regularly.

Cat Problems and how to fix them!

Many people who have cats like to have humidifiers in their home. The problem is, many people don't know they're not necessarily a good idea for cats. Humidifiers are a great way to combat seasonal dryness, allergies, and asthma problems but they can also cause problems in your cat's health. Find out how by reading this article!

1) Dried Up Nose.

Just like people, cats have nasal passages. Now, if you put any kind of moisture into the air (be it steam, mist, or fog) it will naturally be absorbed by the air through evaporation which leaves your cat with a dried up nose. This can cause a lot of discomfort and make them more prone to infection. While this can't happen for every cat because of other conditions they have, it's usually best not to risk it!

2) Allergies and Infections.

This is one of the most common problems that cat owners face when they use humidifiers in their home. It's usually easy to spot because cats tend to have breathing difficulties if they're left in a room that has been artificially humidified. This is especially a problem when the humidity never drops below 60% which makes it too damp for their body.

3) Infections in the Cat's Skin.

When your cat is exposed to humid air, it can cause rashes and other skin issues. This is even more common in cats who are used to breathing through their skin or who have allergies (like many Persian cats do). When they breathe this in, it can make their skin very sensitive like the Persian cat which doesn't tolerate dry air very well at all. Most cats will go through a dry and humid stage where they'll have to slowly adjust to it.

4) Cat Diseases

Another problem that arises when you use a humidifier is the spread of all sorts of diseases. This usually happens to indoor cats like Maine Coon cats, Munchkin cats, Sphynx cats because they're more susceptible to virus and bacteria. If you have pets in your house who are prone to allergic reactions, then you could also be at risk from using a humidifier!

5) Cat Overheating.

Many times people don't think about the implications of using humidifiers in their home with their pets because it's just not something they've ever had an issue with before. However, it's important to think about the fact that many heaters don't work very well in humid environments. This can cause your cat to overheat if you're not careful!

Now that we've talked about some of the problems you might see with your cat, let's talk about what you can do to fix them.

1) Try to adjust your cat's environment first.

Sometimes all you need to change is the humidity level in your home or apartment. If you notice that your cat is having problems with excess humidity, then try using an air conditioner instead of a humidifier which will just put more moisture into the air rather than remove it.

2) Check your cat's nose for dryness.

If you notice your cat's nose isn't as moist and smooth as normal, then they might have a problem with the humidifier. You can take care of this by removing the humidifier from your home for a little while. When you do this, keep an eye on your cat to see if their nose changes back to normal because if it doesn't, it might be a sign that something else is wrong.

3) Check your cat for allergies.

Since many allergic reactions are caused by humid air, it's a good idea to keep an eye on your cat when they're around the humidifier. If you notice them scratching or sneezing more than normal, then there might be a problem with the humidifier. Try using air filters to help alleviate this problem!

4) Purchase an air purifier.

This is a great way for you to ensure that the air in your house is clean and not harmful to your cat or any other pet in your home. Air purifiers will remove any allergens and viruses in the air so your cat won't have to be exposed to them.

5) Make sure you have a good filter.

If you use a humidifier of any kind, then it's absolutely crucial that you use a good filter. Check the filters every day and change them when they need to be changed. It's also important that you empty the water chamber every day as well so it doesn't get very slimy or gross.

Using humidifiers in your home is not necessarily bad for your cat as long as you know what precautions to take first! Keep these tips in mind and your cat will thank you!

Other Questions

Do ultrasonic humidifiers bother cats?

Ultrasonic means a sound that is beyond a human being's hearing. A cats' hearing is above human beings. They can only hear the sound of a small motor inside the humidifier. Dry air affects the cat the same way it affects you.

Although cats groom themselves with saliva regularly, in dry air it’s impossible. Your cat’s fur will and skin will peel off indicating the effects of dry air.

Ultrasonic humidifiers can bother the cat if it’s not used to it. It can even play with it if not well placed. Placing the humidifier in a place where the cat will not interfere with can help it get used to the sound.

Is Steam good for cats?

Cats with congested noses because of cold need steaming. Yes, cats don't like water but steaming is good for them. It helps in unblocking the breathing system due to colds. Dry air in a room can make your cat have air blockage.

Turn on your hot water shower and let the bathroom get filled with steam. Put your cat inside the bathroom and let it stay there for a few minutes breathing the hot air. The humidity inside there helps its noses to unblock. It works like magic in unblocking clogged noses.


Will a humidifier help a cat with congestion?

Humidifiers add moisture to the air. They work in places with very dry air. When cats get congestion due to colds, keeping them in a room with a humidifier for a few days can be of help.

Just like the way humans treat colds and clogged noses, that's the same way cats get treated. A humidifier will moisten the surrounding room air. And make it easier to penetrate through the nose to the lungs. This movement will eventually ease breathing.
