Best Humidifier for Dogs and Cats

In winter, both humans and pets enjoy a warm, cozy spot indoors. Unfortunately, the dry air, produced by the central heating systems hurts not only us but also our four-legged friends. A mist humidifier is a great solution that fights the dry air’s unpleasant side effects. Check out the following post to learn more about the best humidifier for cats and dogs.

How Does Dry Air Affect Your Pets?

Heated, dehydrated air dries out the mucous membranes, especially in the nose, throat and bronchi. This increases the susceptibility to various diseases, as the so-called cilia cannot properly fulfill their natural cleaning function. Viruses and bacteria can so much easier penetrate the body since they thrive in dry air.

Besides causing respiratory tract irritation, dry air contributes to cracked skin, fragile hair, difficulties in getting a good night rest, snoring.

Humidifier Benefits for Cats and Dogs

You can combat dry air effects with a few tricks. The first concerns heating itself. The ideal room temperature for the vast majority of pets, including “exotic animals”, is between 18 and 20 degrees Celsius. So, a first step would imply avoiding to overheat the house. This not only ensures the moisture supply but also keeps the bill in a decent amount. A second step would be frequent and thorough ventilation. Never just tilt the window, but open it completely and close it again after ten minutes at the latest. Fresh air is great for your health and ensures that bacteria and viruses don’t thrive in a stagnant ambient.

Also, consider buying a humidifier. You can opt for simple models, that you just fill with water hung on the radiator. Or you can benefit from the latest tech and choose a modern humidifier for a more satisfying user experience.
A relative humidity of 45% in the living spaces is optimal for people and animals. You can monitor the humidity levels in your home by using a hygrometer and some humidifiers have such a device incorporated.

Best Humidifier for Dogs and Cats

Our personal option when it comes to the best humidifier for dogs and cats is a humidifier/air purifier combo. This versatile appliance has more pros than cons and we develop both aspects in the paragraph below.

Pros of An Air purifier-Humidifier Combo

  • It has a complex action that not only humidifies dry air but also purifies it by removing dust, pollen, pet dander and other allergens. It makes it possible to enjoy healthy, fresh air in your home.
  • Ideal tool for removing stench, smell, germs and smoke particles making room deodorants obsolete and guarding you against unwanted chemicals.
  • This appliance even freshens up the air after cooking which we find pretty neat since most modern homes embrace an open space design. Also, our pets and their food don’t always have the most attractive odor.
  • Using such a device improves breathing for both humans and pets, providing comfort for the different respiratory tract conditions: allergies, snoring, asthma, sinus infections, etc.
  • These appliances are a great add-on for the households situated close to roadways, business ranges and heavily used boulevards, where the ventilation would bring more disadvantages, due to the high pollution in these areas, than benefits. These gadgets have a real contribution to neutralizing destructive gas mixes.

Cons of An Air purifier-Humidifier Combo

  • Air purifier-humidifier combos are usually more pricey than a humidifier or purifier unit. But you should keep in mind that you actually invest in two appliances combines, which in the end mean less energy consumed and less space occupied.
  • High maintenance – considering the above premise of two devices combined, you generally have to invest twice maintenance, mostly in filters.

Let’s see some competitive models so you can have a clearer image of what owning an air purifier-humidifier combo implies.
