If not well treated, it could become life-threatening. This is why we recommend you purchase the best dehumidifier for mold allergies to help remove contaminants from the air from your environment.

Hot seasons come with high humidity, providing a conducive breeding environment for bacteria, viruses, and dust mites. These agents are responsible for one allergy trigger or another, like dust mites, especially triggering symptoms for asthma and COPD.

In dealing with the high humidity level, one can make use of a dehumidifier to ensure the moisture content in the atmosphere is always around 35 – 55% (recommended for healthy living), and if by chance or research you know the specific allergen present in the home, for example, dust mite, then purchase the best dehumidifier for dust mites (the allergy you want to combat).

Generally, you should look for a product that can adequately deal with all or at least most of the common allergens just to be safe, but the best humidifiers for allergy sufferers always have certain specifications which you must know to properly select the right product. It is, for this reason, this article is written, read through and you would be well equipped with all the information you need.

Consideration for picking the best dehumidifier for COPD and Asthma

The capacity of the dehumidifier:

This refers to the amount of water vapor a dehumidifier can remove daily from the atmosphere. For example, a 60-pint dehumidifier can fire 60 pints of moisture from the atmosphere each day. Depending on the humidity level in your environment, purchase a suitable humidifier that can efficiently remove moisture, keeping it at a safe level.

Also note that the dehumidifier’s capacity doesn’t refer to the maximum amount of water the water tank can hold, as that depends on the manufacturer’s design and the tank’s actual size. Dehumidifiers with larger capacities generally have a more comprehensive coverage area than those with lesser degrees but also know that the tank emptying interval is higher except for those with continuous draining options.

Noise level:

The fact that a dehumidifier would produce a specific sound while in operation is almost unavoidable due to the movement of its compressor fan. The noise level, however, differentiates the noisy from the quiet, and it depends on the quality of the dehumidifier.

You can always choose to go for products with less noise, which we advise to reduce disturbances in the home and increase comfort. Most dehumidifiers, however, come with a fan speed-varying feature that allows you to increase or decrease the fan speed and control the noise levels.

Automatic features:

As discussed in some of our product reviews, modern dehumidifiers comes with sever automated features that make usage more accessible and very convenient. Like the timer, anti-frost, auto restart, clean filter alert, water tank full alert, and even autoregulation. It would be great to have most, if not all, of these features in the machine.

Level of energy consumption:

Generally, a dehumidifier is expected to draw a certain amount of energy primarily when it works in a place with a high level of humidity for a long duration of time, which already guarantees an increase in your electric bills.

Before selecting a product to purchase, however, ensure the amount of energy it consumes isn’t too much. Going for an energy saving unit is also a great plus, along with the automatic regulatory feature that switches it on and off, saving energy costs and relieving the stress on the machine.

COPD and rainy Weather: Best weather for COPD

When it comes to the treatment of COPD, the climate around you plays a very vital role, meaning that depending on several factors in the atmosphere, it could either be relieved or aggravated.

Extreme cold weathers can be dangerous for those living with COPDS, as the winds during that period are more difficult to breathe in and could cause fatigue or shortness of breath. Cold weather has also been linked to increased COPD hospital cases.

Topical weathers, on the other hand also, doesn’t ease the difficulties of COPD patients, as breathing in hot air can worsen lung way inflammations, therefore, worsening the disease. This is as a result of high humidity levels, causing an increase in water vapors in the air, making breathing ultimately more painful.

High humidity levels also support the growth of mold and bacteria in the environment, which when airborne and inhaled, compounds the already existing COPD struggles.

In seeking friendly weather, studies have shown that the temperatures should be generally mild and free of pollution, moderate humidity, and low-temperature levels. What better weather to find these climate conditions for COPD.

Is humidity good or bad for COPD?

Humidity in itself isn’t a bad condition for COPD , but when it reaches high levels like during the hot periods where sweating and dripping is ban to occur, it becomes harmful.

Like I stated earlier, high humidity means more water vapors in the atmosphere which makes breathing more complicated than it already is for COPD patients, and it also supports the growth of harmful airborne organisms that should be avoided at all costs.

Humidifier or Dehumidifier for allergies and asthma

The main question to answer this is: do I need more humidity in the atmosphere or a lesser amount than I already have?

A humidifier adds moisture to the atmosphere to increase the humidity level while a dehumidifier removes water vapor from the atmosphere to reduce the humidity level.

When dealing with allergies and asthmas, a high humidity level (about 35 – 55% humidity level as prescribed medically) favors the growth and survival of harmful organisms like mold which could be triggers for allergic reactions, meaning you would need to regulate the number of water vapors in the air to a conducive level.

On the other hand, extremely low humidity conditions aren’t advised for asthma and COPD patients, as the cold air can irritate airways, causing muscles inside to spam and therefore making breathing more difficult. Dry air also assist in the survival of dust mites which are chief triggers of asthma

In this case, depending on your environment, you should use a suitable device i.e., for extremely low humidity conditions, use a humidifier and under really high conditions makes use of a dehumidifier.

My submission here is that either humidifier or dehumidifier is good or bad for COPD and asthma allergies, all you can do is to study your environment for you to choose the perfect unit to go for. Preferably, you can get the 2 device and opt of anyone as the need might be.
