Low-price H13 replacement filters for Blueair Max owners

Is the PUREBURG Replacement Filters Compatible with BLUEAIR Blue Max 3250 auto & 3250i worth buying? Yeah, if you’re after a compatible 2-pack at the current £39.22 all-time low and want H13 HEPA plus activated carbon filtration without paying for the original-brand filter, it’s a solid deal. The main draw is pretty clear: you get two replacement filters, a 4.6/5 rating from 37 reviews, and a price sitting 15.4% below the £46.34 average.

First impressions

PUREBURG really targets a specific buyer here—Blueair Max owners who just want a cheaper replacement that still claims H13 True HEPA performance. The listing says these filters fit the Blueair Blue Max 3250 auto, 3250i, Blue Pure 411i Max, and 411a Max.

That compatibility list is more important than the branding, honestly, since these aren’t universal filters. The product is not compatible with 411, 411+ and 411 Auto.

If your purifier’s on the list, this is just a simple two-pack replacement, not some fancy upgrade.

What do you actually get?

You get a 2-pack of H13 HEPA + activated carbon 2-in-1 filters. The H13 rating is the main spec here, with the listing claiming it’ll capture 99.97% of airborne dust and PM2.5 down to 0.3 microns.

That’s the right filtration standard for most indoor pollution—dust, fine particles, the stuff that really matters during UK pollen season, winter months with closed windows, or those damp days when the air just feels stale.

The activated carbon layer helps with odours and gases, which is handy if you’re dealing with cooking smells, pet odours, or a bit of mustiness from mould-prone rooms.

You can swap the filter out tool-free in about a minute, which is exactly what most people want from a consumable part.

How does it perform in real use?

Looking at the data, this filter stands out as a practical, budget-conscious replacement rather than a premium accessory. H13 HEPA plus carbon is a good combo for catching fine particles and cutting down everyday household odours.

For UK homes, that means it’s relevant for spring pollen, traffic pollution if you’re near busy roads, and those dust spikes that show up when the heating comes on in autumn and winter.

Keep in mind, it’s just a replacement filter, not a purifier itself—so you need to fit it correctly, replace it regularly, and make sure your machine’s in good shape.

PUREBURG recommends cleaning the filter monthly with a soft brush. That tells you the filter’s meant to be maintained, not just forgotten about.

Build quality and ease of use

The listing promises top-notch quality and says you can change the filter in a minute with no tools. That’s reassuring if you want a quick swap, especially if you’re changing filters in a bedroom, home office, or living room.

There aren’t many construction details beyond the H13 HEPA and carbon layers, so it seems more focused on function and convenience than heavy-duty engineering.

You really need to check your exact Blueair model before ordering. The product clearly says it’s not compatible with 411, 411+ and 411 Auto, and that detail can save you from an annoying return.

Is it good value for money?

At £39.22 for two filters, the price is competitive. It undercuts the Xiaomi Mi Air Purifier Antibacterial Filter at £41.98 and the Xiaomi Mi Air Purifier HEPA Filter at £39.99, and it has a slightly higher rating at 4.6/5.

It’s also cheaper than the Philips Original Replacement Filter at £45.26, though Philips plays in a different, more premium space.

The value looks even better since the current price is the lowest ever recorded, well below the historical high of £67.75.

How does PUREBURG compare to alternatives?

Compared to the Xiaomi options, PUREBURG sits in the same price bracket but gives you a 2-pack, so the per-filter value is better if you own a compatible Blueair purifier.

Against Philips, it’s £6.04 cheaper than the £45.26 original replacement, though the Philips filter is for a different set of purifiers and might appeal more to people who want original-brand parts.

The trade-off is pretty simple: PUREBURG offers a lower-cost compatible option with strong user feedback, but doesn’t have the original-manufacturer reassurance you get with Philips.

Bottom line on performance and value

If you already own a compatible Blueair unit, this replacement filter just makes sense. It’s got the essentials: H13 HEPA, activated carbon, comes as a two-pack, and the price is currently at an all-time low.

With a 4.6/5 rating from 37 reviews, it seems most buyers walk away happy. Plus, 50+ bought last month—that’s a solid sign people keep coming back for it.

Just make sure to double-check compatibility, since the listing clearly spells out which 411 variants won’t work.
