How To Save Water With Your Humidifier

Using a humidifier is synonymous with water wastage. Yet, how many of you thought of this? Your logic is probably not aligned with the choice of products and the implementation aspect. 

You can save tons of water with your humidifier by following these steps:

  • Go for a centralized humidifier that maintains the humidity in all rooms simultaneously. 
  • Recycle and reuse water instead of draining it. 
  • Choose a product based on its Energy Star rating
  • Install products like WaterSavor that can lower water wastage and improve energy efficiency. 

These approaches can save at least 70% more water. Practice them regularly, and you can go zero-waste sooner!

What Are Alternatives To A Humidifier?

We recommend choosing humidifier alternatives over buying a humidifier when you want to go zero-waste on all aspects. 

Want to humidify your home without a humidifier? Here are our solutions for each part of your sustainable home: 

  • Include houseplants that can regularly humidify your living spaces. 
  • Use a stovetop to humidify your kitchen. 
  • Set up cross-ventilated windows that can circulate, humidify, and purify indoor air.  

These are perfect alternatives that are zero-waste, energy-efficient, and free of cost. 

Do Humidifiers Need To Be BPA-Free?

Buying a BPA-free humidifier takes you one step closer to the vision of a sustainable home. However, you can diffuse BPA (bisphenol A) from your humidifier when you need it.

Conclusion

The air quality of a sustainable home is often underestimated. In this article, we have presented nine of the best eco-friendly and energy-efficient humidifiers to help improve it.

However, despite our recommendations, ideally we suggest using humidifier alternatives as those truly are zero waste. 

List your needs, choose the product/idea for a humidifier, and then go for it! Once you do, you can breathe better and more naturally!
