Are Portable Air Conditioners Safe to Use?

Portable air conditioners are safe to use, just like many improved devices. However, any electrical appliance requires safety measures. If you are looking for the safest and the most convenient option, consider using an evaporative air cooler instead of a portable air conditioner.

Evaporative air coolers by Evapolar are less dangerous on many levels — they use way less energy, they don't use freon-like liquids, and they don't contain any easily removable details. These powerful devices are also safe for your skin and mucous — since they don’t remove humidity from the air, they don’t dry out your mucous membranes.

10 Safety Tips for Using Portable Air Conditioners

1. Read the instructions

Always read the manufacturer's instructions carefully before using a portable air conditioner — they exist for a reason! You will find the safety measures and the best practices to ensure you get the most efficient cooling.

2. Ventilate

Make sure the air conditioner is in a well-ventilated area, and never cover the vents with anything. The first rule of portable AC safety is that they need to exhaust the hot air outside.

3. Place the device in a safe spot

Do not place the air conditioner near a fire escape or where it will block traffic.

4. Keep children and pets away from the air conditioner

Always check the instructions for the minimum age to operate the device.
As for your furry friends, they indeed enjoy the cool air, especially in summer. However, it's better not to leave them unattended with the portable air conditioner.

Evaporative air coolers are a much safer option for pets!

Also, they provide gentle, natural cooling that won't result in the infamous air conditioning sickness — one of the most common dangers of portable air conditioners.

5. Never put the portable air conditioner in a closed space, such as a closet

This can be extremely dangerous because the appliance will start overheating and quickly catch on fire.

6. Use an extension cord if necessary, but choose the right one

If you must use an extension cord with your portable air conditioner, make sure it is a heavy-duty cord designed for outdoor use. The thicker the cord, the better — that way, you will reduce the risk of electrical fires.

Some devices cannot be used with any type of extension cord, so make sure to double-check it in the safety manual.

7. Check for damages before using the portable air conditioner

Before each season, check your portable air conditioner for any cracks or damages. If you notice anything unusual, do not use the device and contact customer support immediately.

8. Unplug when you leave home

Always unplug the air conditioner when not in use.  If you plan to be away for an extended time, it's better to unplug and store it in a dry, safe space.


9. Do not use a portable air conditioner with a generator

Using a portable air conditioner with a generator can lead to fires and other dangers. The generator's size, age, and power can be incompatible with the AC — if your generator isn’t powerful enough to handle the AC, don’t plug it in.
If your generator wattage is too small for the portable air conditioner, you risk damaging your generator, AC, or both.

10. Regularly clean the device

To ensure optimum efficiency, clean your portable air conditioner regularly. This will also help you spot any damages early on. A clean device means clean air, and with proper maintenance you ensure your family enjoys bacteria-free air.

Ensure you follow the maintenance instructions — a well-maintained device will serve you for a long time! If you are missing your instruction, go back to our old friend Google, or use a website with a database of safety instructions.

If you experience any problems with the air conditioner, stop using it and contact the manufacturer immediately.

Can A Portable Air Conditioner Cause Carbon Monoxide Poisoning?

No, a portable air conditioner cannot cause carbon monoxide poisoning. Carbon monoxide is produced when gasoline, wood, and coal burn. Portable air conditioners do not use any of these fuels.

Do Portable Air Conditioners Use Ozone?

No, portable air conditioners do not use ozone. Ozone is a gas used in some industrial applications to clean the air. However, it is not used in portable air conditioners.

Safety Tips for Portable Evaporative Coolers

Evaporative air coolers cool the air by taking the water through pads and exhausting cool air. Evaporative air coolers require less maintenance than portable air conditioners and are safer to use.

However, they also come with safety tips!

1. Read the instructions

We had to repeat this one! In the instructions, you will also find recommendations on maintenance and cleaning, which will help you keep the device working correctly.

2. Keep the cooler clean (inside and outside)

Remove the dust from the air grills regularly. This is for proper functioning and safety — you don't want to inhale dust! A build-up of dirt will make the cooler less effective and can also be dangerous for your health.

A clean cartridge guarantees your safety and the cooler's longevity! If your device uses a cartridge, like Evapolar, then replace the cartridge every 3 to 6 months, depending on how often and where you use the air cooler. For other air coolers, refer to the instructions, and you won’t get it wrong.

4. Don't use the cooler near water

Keep the evaporative air cooler at least 3 feet away from any water source, such as a swimming pool, to avoid electrical hazards. Don’t let pets or kids too close to the device.

5. Ensure proper storage

If you have decided to store your air cooler for a long time, clean and dry the device first. Then, place the air cooler in appropriately sized packaging for storage. Store the device in a dry space at room temperature.

6. Use clean water only

Use ONLY clean water in your air cooler. Do not add any scents or essential oils, and use filtered water. If you don’t use the cooler for more than two days, don’t leave the water inside. If you forget, remove the stale water before using the cooler again.
