Deal 2 – Get 15% off your first AirFanta replacement filter subscription delivery

How much can you save with a subscription?

Let’s say you order an AirFanta 3Pro Replacement Filter (High Efficiency) every 12 months. That will cost you S$84 a year before discounts.

If you opt for a subscription instead (with deliveries made every 12 months), you will save 3% off the full price, or S$81.48 a year.

With our special offer, you get 15% off the first delivery, so you’ll pay just S$69.26 for the first delivery, and S$81.48 for subsequent deliveries.

What are the benefits of a filter replacement subscription?

1. Set and forget – gone are the days where you have to remember when to replace your filters. Simply subscribe and they’ll be delivered to your doorstep when it’s time to replace
2. Convenience – decide how often you want to receive your filters – the choice is up to you
3. Save more – replacement filters are offered at a lower cost in subscriptions compared to buying individually, even before coupons
4. Free shipping – regardless of order value, all replacement filters come with free shipping, helping you save even more
