Frequently Asked Questions

Answers about the Serava™ Plug-In Air Ionizer, safety, and how to get the best results in your home.

• How does the Serava™ Plug-In Air Ionizer actually work? +
  Serava releases tiny negative ions into the air. These ions attach to floating micro-dander, dust, and other particles, making them clump together and become heavier. That helps them fall out of the breathing zone or get trapped by normal household surfaces, so the air around your family feels easier to breathe.
• Is it safe to use around kids, cats, and dogs? +
  Yes. Serava is designed for everyday family homes. It uses a low-energy ionization process and does not release chemicals, scents, or ozone. Just plug it into a standard outlet and keep it away from small hands or paws, the same way you would with any other plug-in device.
• Will this replace my regular air purifier? +
  Serava focuses on the “floating” problem by helping remove micro-dander and fine particles right in the breathing zone. Many customers use it on its own in smaller rooms, or together with a HEPA purifier for an extra layer of support in larger spaces or high-traffic areas.
• How many devices do I need for my home? +
  As a simple guide, we recommend 1 device for bedrooms or small rooms, 2 devices for open-concept living areas, and 3+ for multi-pet homes or multiple floors. Most customers start with 2–3 units and place them where family and pets spend the most time.
• How long until I notice a difference in the air? +
  Most homes start to notice a change in “air feel” and stuffiness within 24–72 hours of continuous use. For homes with heavy pet dander or long-standing odors, we suggest running Serava 24/7 for at least 7 days to allow ions to work through the space.
• Does it use a lot of electricity? +
  No. Serava is ultra-low power — similar to running a small LED night light. You can leave it plugged in 24/7 without worrying about your power bill.
• Are there filters or refills I need to replace? +
  No filters, pads, or cartridges are required. Simply plug Serava in and occasionally wipe the outer shell with a dry cloth to keep dust from building up on the device itself.
• What if it doesn’t work for my home? +
