Frequently Asked Questions

Is Subscribe & Save actually cheaper than a one time order?

Subscription orders automatically include up to 8% off every shipment plus free delivery, which frequently beats a one time discount code over the life of a subscription. Promotional discount codes are not valid on Subscribe & Save orders since the subscription discount already applies.

Does Air Filters Delivered offer free shipping?

Free shipping has applied to orders once a cart reaches a set threshold, and subscription orders get free delivery automatically regardless of order size.

Can I return a custom sized air filter?

No, custom sized filters are made to order and are not eligible for return. Standard, non custom filters can be returned within 30 days in their original condition and packaging.

How are refunds processed on returns?

Refunds go back to the original payment method, minus the cost of shipping. Orders over $250 also carry a restocking fee, so it is worth confirming that detail before returning a large order.

Does Air Filters Delivered price match?

Yes, if the same filter is found for less elsewhere, Air Filters Delivered has offered to match that price, which can be worth checking before assuming a competitor's listing is the better deal.

What does the referral program pay out?

Referring a friend has given the new customer a discount on their first order of $40 or more, while the referrer receives reward points credited to their account once that purchase completes.

Is there a discount for signing up for the newsletter?

Yes, subscribing has unlocked a percentage off a first purchase, along with early access to sales and HVAC maintenance tips like optimal replacement schedules based on MERV rating.

How do I avoid ordering the wrong filter size?

Measuring the length, width, and depth of the existing filter before ordering is the most reliable way to avoid a mismatched size, since getting it wrong means dealing with a return and, on custom sizes, no return option at all.

Saving Guide

Why a subscription usually beats a one time discount

Because Subscribe & Save already bundles an ongoing discount with free delivery, and one time promo codes cannot be applied on top of it, a household that replaces filters on a predictable schedule generally saves more by subscribing than by chasing seasonal codes.

Getting the size right before you order

Since custom sized filters cannot be returned at all, and standard filters lose shipping costs on a return, measuring the length, width, and depth of your current filter before placing the order is the cheapest insurance available here.

Using price match instead of shopping around

Rather than comparing prices across multiple retailers before buying, requesting a price match on a specific listing found elsewhere accomplishes the same goal with less effort, since Air Filters Delivered has matched competitor pricing directly.

Timing a first order around the newsletter and referral offers

Combining the newsletter's first order discount with a friend's referral code, when both are available and stackable, can meaningfully lower the cost of a first subscription setup before the recurring discount even kicks in.

Managing large orders to avoid restocking fees

Orders over $250 have carried a restocking fee on returns, so splitting an unusually large one time purchase into a couple of smaller orders can reduce exposure if a return ends up necessary.

Checklist before checkout

Measure your existing filter's exact dimensions before ordering, choose Subscribe & Save if you'll need refills on a schedule rather than stacking a promo code that won't apply anyway, request a price match if you've seen the same filter cheaper elsewhere, and keep original packaging until you're sure a standard size filter fits correctly.
