On our previous blog post about Do Indoor Plants Reduce Humidity? Best Plants for Condos with Pets. We talked about the basics or factual information about having indoor plants in your Condo Unit.

 I'd like to share more about it, as I keep researching and finding ways to improve the humidity naturally, with plants and without other stuff that I need to always buy in the market. 

But I haven't shared that my real goal is to prevent or reduce dust mites/bed mites. 

Dust mites are tiny, insect-like bugs that like to live in warm, humid places. They don't bite like bed bugs do; instead, they eat dead skin cells that are in household dust. The main problem they cause is that their waste and decaying body parts can cause allergic reactions.

Going back, multiple threads talk about plants that “absorb humidity.” The idea usually comes from how plants interact with moisture, but the science is a bit different from what those posts imply.

Plants take water from soil and release it through Transpiration.

Because of this process, most plants actually add a small amount of moisture to the air, especially leafy plants like Pothos [my most favorite and low maintenance indoor plant].

Some plants can absorb moisture on their leaf surface, but the amount is very tiny compared to room humidity. That’s why they can’t function like a real dehumidifier.

A few plants are often mentioned online because they tolerate humidity well or don’t release much moisture:

• Snake Plant
• Peace Lily
• Boston Fern
• Tillandsia

But even these won’t noticeably lower room humidity. For my real goal, which is to reduce bed mites, I will need to ensure these TWO important things:

1. They thrive at 70–80% humidity
2. They struggle when humidity is below ~50–55%
