Yes, DampRid works like a dehumidifier in that it removes excess moisture from the air. However, it is an unpowered chemical desiccant rather than a mechanical appliance. Instead of using electricity, a fan, or a compressor, DampRid uses calcium chloride crystals to passively absorb humidity and collect it as liquid.
Choose DampRid for small, enclosed spaces without electricity, or electric dehumidifiers for continuous, whole-room humidity control. DampRid is cheap and passive, but dehumidifiers cover large areas, remove moisture much faster, and don't require constant refills.
Yes, a dehumidifier can be highly beneficial for managing COPD, provided your home has high humidity. It makes breathing easier by lightening the air and preventing mold and dust mites, which are common respiratory triggers.
“Within three days, DampRid reduced humidity to 43% and collected almost half a cup of water.”
You can substitute a dehumidifier with natural moisture absorbers like calcium chloride, silica gel, or activated charcoal. You can also use household items like baking soda or rock salt, or adjust your daily habits by improving ventilation, using your air conditioner, and running exhaust fans.
The cheapest way to dehumidify a room is by improving natural ventilation and using homemade moisture absorbers. You can easily create a DIY unit using a plastic colander, a bowl, and calcium chloride crystals, or use simple household items like coarse salt, baking soda, and charcoal.
Rock salt: Place bowls of rock salt in damp areas like closets or basements. It draws in moisture and requires no energy. Charcoal briquettes: Like rock salt, they absorb humidity and can be placed discreetly around the home.
So, why is your house so humid, and what causes high humidity indoors? The short answer is that more moisture is being trapped indoors than your HVAC system can remove. Air leaks, poor ventilation, or an air conditioning system that's not working correctly can all exacerbate the issue.
Yes, dehumidifiers frequently get moldy. Because they pull moisture from the air and store it in dark, cool collection tanks, they provide an ideal environment for mold and bacteria to thrive if not properly maintained.
To naturally dehumidify a room, increase ventilation by opening windows on dry days, use interior fans to circulate air, and place moisture-absorbing materials like coarse sea salt, baking soda, or bamboo charcoal in problem areas. For small spaces, you can also use calcium chloride in a colander-and-bowl setup.
Avoid using a dehumidifier if your indoor relative humidity (RH) is already between 30% and 50%. Running one below this range, in freezing temperatures, in drafty open-window scenarios, or in extremely dry climates will waste energy and dry the air to unhealthy levels.
Neither extreme dry nor extreme humid air is best for COPD; the ideal environment is moderate humidity, typically between 30% and 50%. Excessive humidity makes air feel heavy and harder to breathe, while too little humidity dries out airways and causes irritation.
Some of the main things you'll be advised to do are outlined below.
The best places to put DampRid are in small, enclosed, or high-humidity spaces with stagnant air, such as closets, bathrooms, laundry rooms, and pantries. Place it on a flat, stable surface (like a high shelf) or hang it out of reach of children and pets.
Yes, dehumidifiers are supposed to reduce excess moisture, but sometimes they get a little overzealous. If the humidity level is set too low, it can leave you with itchy skin, dry eyes, or a scratchy throat. And while you can always slather on lotion or keep a glass of water nearby, it's hardly a long-term solution.
Replace DampRid every 30 to 45 days, or sooner if you notice the calcium chloride crystals have completely dissolved and the bottom chamber is full of liquid. The exact timeframe depends on your local humidity levels and temperature.
To eliminate mold spores in the air, use a HEPA air purifier to trap them, and UV-C light to destroy their DNA. For immediate, natural relief in small spaces, you can diffuse antimicrobial essential oils like tea tree oil.
Early stage black mold symptoms primarily mirror common allergies. You may experience sneezing, coughing, red or itchy eyes, nasal congestion, and a scratchy throat. A key indicator is that these symptoms often worsen while you are at home but improve when you leave the environment.
Dehumidifiers improve respiratory and allergy symptoms by removing excess airborne moisture. This controls the spread of mold, mildew, and dust mites. However, overusing a unit can make the air too dry, leading to dehydration, irritated sinuses, and dry, itchy skin.
Signs of High Humidity
Condensation on Windows: If you notice water droplets on the inside of your windows, it's a sign that there's too much moisture in the air. Mold Spots: Mold loves damp environments. If you're spotting mold in corners, on walls, or in the bathroom, your home's humidity is too high.
Initial drying: When using a dehumidifier in a damp space for the first time, run it continuously for 24 to 48 hours on a low humidity setting (around 30%) to thoroughly dry the area. Regular use: To maintain a comfortable humidity level (30–50%), running the dehumidifier for 8 to 12 hours per day is often sufficient.
Opening a window can reduce indoor humidity—but only if the outside air is cooler and holds less moisture than the inside air. To check if it will help, look at the local Weather Forecast: if the outdoor dew point is below 60∘F60 raised to the composed with power F𝟔𝟎∘𝐅, opening a window will usually lower your indoor humidity.
To draw moisture out of a room, use a dedicated dehumidifier, or natural absorbers like DampRid, calcium chloride, and baking soda. Active methods include ventilation with fans, air conditioning, and placing desiccants like silica gel in enclosed spaces.
The cheapest and most effective homemade moisture absorber uses calcium chloride (sold as bulk driveway ice melter) combined with a simple two-bucket or colander-over-bowl system. This DIY approach costs a fraction of commercial products like DampRid and works identically to pull water from the air.
