Fit & Compatibility

How do I know if this filter fits my fridge?
Use our “Compatibility Check” on the website. Enter your fridge’s model number and we’ll show you the exact filter you need.

Where can I find my fridge’s model number?

Most fridge model numbers are on a label inside the fridge (usually behind the crisper drawer, on the side wall, or near the door frame). See our guide here. If you can’t find it, check your user manual.

What if the filter doesn’t fit?


You’re covered by our Perfect Fit Guarantee. If it doesn’t fit, we’ll replace it or refund you, no hassle.

Can I use a non-OEM filter in my fridge?

Yes, Certified Compatible Filters are engineered to meet or exceed OEM standards, while offering the same fit and filtration performance—at a better value.

Usage & Maintenance

How often should I replace my filter?

Every 6 months, or sooner if your water has a noticeable taste or odour.

How do I install the filter?

Each filter comes with step-by-step instructions. Most simply twist or click into place—no tools required.

What happens if I forget to replace it on time?


Old filters can clog, slowing water flow and letting impurities through. Regular replacement ensures fresh, clean water and ice.

How do I know when my filter needs changing?


Look out for:

  • Water tasting or smelling off
  • Slower water flow
  • Your fridge’s “change filter” light switching on

Performance & Safety

Do these filters remove chlorine, lead, and microplastics?


Yes, our filters reduce chlorine, lead, and other common contaminants, including microplastics, so your water tastes better and is safer to drink.

Is water in the UK safe to drink without a filter?


Tap water in the UK is safe and regulated. A filter isn’t required—but it improves taste, reduces micro-contaminants, and gives extra peace of mind.

What’s the difference between OEM filters and Filter Flair alternatives?


OEM = “Original Equipment Manufacturer.” Filter Flair alternative filters deliver the same quality, compatibility, and certifications, but at a fraction of the price.

Are your filters certified (WRAS, NSF, WQA)?


Yes, all Filter Flair filters are independently tested and certified to meet WRAS, NSF, and WQA standards.

Delivery & Subscription

How quickly will my filter be delivered?


Orders are processed within 1 business day. Express UK delivery arrives in 2–3 days, and Next-Day delivery is available if you order before 3pm. For more information visit our shipping policy page

How does Subscribe & Save work?


Pick your filter, and get it delivered every six months while saving up to 10%. 

Can I pause or cancel my subscription anytime?


Yes, you’re in control, you can pause, change, or cancel anytime from your account dashboard.

How does international shipping work?


We ship worldwide. Costs and delivery times vary depending on the destination—calculated at checkout. See more information on our shipping policy page
