How It Works: From Purchase to Home
Updated June 2026
Welcome! We’re thrilled you’re considering a Coway machine for your home. Whether you’re looking to rent or purchase a drinking water system or an air purifier, here’s exactly what to expect every step of the way.
Step 1: Deciding to Rent or Purchase
Renting a Machine:
- Your machine will require maintenance about once a quarter.
- Depending on your lease term (3, 5, or 6 years), all filtration changes are free for the duration of your lease.
- A Coway technician will visit your home to service your machine at no extra cost — no delivery fee, no materials fee, no service fee.
Purchasing a Machine:
- When you purchase outright, you’re covered for one year on machine servicing, warranty, and filter replacements.
- After the first year, you’ll need to purchase your own filters. Our technician is still available for servicing.
Step 2: Placing Your Order
- Call or contact Sandy at (213) 239-3249 to confirm the model that’s right for your home.
- Once your order is placed, a Coway Customer Service Representative will call you to coordinate your installation time.
A note on identity verification: For rental agreements, we run a quick soft credit check — standard for any lease arrangement. You’ll need to provide your Social Security Number for this step. We know that can feel like a big ask, so we’ve written a full explanation of why we ask, what we do (and don’t do) with it, and why it won’t affect your credit score.
👉 Why Coway Asks for Your Social Security Number — and Why It’s Nothing to Worry About
Short version: it’s a soft inquiry only, has zero impact on your credit score, and does not appear on your credit report.
Step 3: Delivery and Installation
Your Coway machine will be delivered and installed at the agreed date and time by our technician. Please make sure someone is home to allow entry.
Step 4: Enjoying Your Coway Machine
- Start using your machine to enjoy clean, purified water or air right away.
- For rental customers, quarterly maintenance will be scheduled — our team will reach out as your service date approaches.
Step 5: Filter Replacements and Servicing
- Rental: Filter replacements and servicing are fully included. A Coway technician handles everything.
- Purchase: Covered for the first year. After that, filters are available on our website and servicing can be scheduled as needed.
Step 6: Additional Filters
If you ever need to purchase filters directly:
Filter names are listed in each product description on our products page.
