Replacement filters can look almost identical online, but a small compatibility mistake can leave you with a filter that does not seal or fit your purifier correctly. The 5510 5520 Replacement Filter Q Compatible Set is made for Winix 5510 and 5520 air purifiers and combines HEPA filtration with an activated-carbon stage. This particular Amazon ASIN is a third-party compatible replacement rather than a genuine Winix-branded Filter Q. It makes sense if you want a multi-filter replacement pack, but you should confirm your purifier model before ordering.
Quick Verdict
Rating: Recommended with caveats
Best For: Winix 5510 or 5520 owners who want a third-party HEPA and activated-carbon replacement set.
Bottom Line: The set covers the two main replaceable filtration stages used by compatible Winix purifiers and gives you multiple filters in one pack. The main tradeoff is that it is a compatible aftermarket product, not the genuine Winix Filter Q, so exact model checking matters.

What Is the 5510 5520 Replacement Filter Q Compatible Set?
This replacement set is designed to fit the filtration compartment of compatible Winix 5510 and 5520 air purifiers. It is sold as an aftermarket alternative to Filter Q, part number 1712-0123-00.
The package combines a pleated HEPA filtration stage with an activated-carbon stage. The HEPA layer is intended to capture fine airborne particles such as dust, pollen and pet dander, while the carbon layer targets household odors and fumes from sources such as cooking, pets and smoke.
The package format is also worth noting. You receive two HEPA filters and two activated-carbon filters rather than a single replacement pair. That can be convenient if you plan to keep the same purifier for an extended period, although actual replacement timing still depends on your environment and purifier usage.
Before You Buy: Check the exact model number printed on your purifier. This listing is marketed for Winix 5510 and 5520 units and should not be treated as a universal Winix filter. It is also a third-party compatible product, not the genuine Winix-branded Filter Q.
Who Should Buy It?
Best For
- You own a Winix 5510 or 5520 and need replacement HEPA and carbon stages.
- You prefer buying two replacement sets together instead of one filter pair at a time.
- You are comfortable using a compatible aftermarket filter rather than an OEM Winix filter.
Skip If
- Your purifier model is not specifically listed as compatible.
- You only want a genuine Winix-branded Filter Q replacement.
- You need independently verified performance beyond the seller’s stated HEPA specifications.
HEPA Filtration Performance
The HEPA stage is the main particle filter in this replacement set. The product claims 99.97% filtration of particles as small as 0.3 microns, which covers common airborne particles such as dust, pollen and pet dander.
That specification is useful if visible dust and airborne allergens are your main concerns. However, a replacement filter only performs properly when it fits securely in the purifier. Gaps around the frame can allow air to bypass the filter media, which is why model compatibility should matter as much as the filtration percentage printed on a listing.
You should also avoid treating the filtration percentage as a guarantee that every particle in an entire room will be removed. Overall room performance depends on the purifier’s airflow, fan setting, placement, operating time and how quickly new particles enter the space.
Activated Carbon and Odor Control
The second replaceable stage uses activated carbon. Its job is different from the HEPA media. Instead of focusing primarily on solid particles, the carbon stage helps reduce unwanted household odors and fumes.
This can be useful in homes with cooking smells, pets or occasional smoke. Carbon capacity is not unlimited, however. Once the carbon becomes saturated, odor performance can decline even if the filter still looks clean.
That is one reason replacement timing should be based on both the purifier’s filter indicator and your actual indoor conditions rather than appearance alone.
Fit and Compatibility
The strongest reason to consider this product is its focused compatibility with the Winix 5510 and 5520. Both purifier models use Filter Q as their specified replacement filter family, and this aftermarket set is sold as a compatible substitute for part 1712-0123-00.
Do not buy based only on the visual shape of the filter. Winix sells several filter families for different purifier models, and similar-looking filters are not automatically interchangeable.
Pro Tip: Read the model label on the purifier itself before ordering. Matching “5510” or “5520” is more reliable than comparing photos or assuming that another Winix model uses the same filter.
Installation and Setup
Replacing the filters in a 5510 or 5520 is a relatively simple maintenance task. Turn the purifier off and unplug it before opening the front panel. Remove the used filters carefully so trapped dust is not shaken back into the room.
For the purifier’s normal filter arrangement, the HEPA stage sits toward the back, the carbon stage sits in front of it, and the reusable pre-filter remains toward the front. Make sure each stage is seated evenly before replacing the front panel.
After installing the replacement filters, follow the purifier’s reset procedure so its filter indicator can start a new maintenance cycle. The Winix manual instructs you to use the filter-reset control after replacement.
Common Installation Mistakes to Avoid
- Do not install a filter without first confirming the purifier model.
- Do not leave protective packaging on a new filter.
- Do not force a filter that does not sit flat inside the compartment.
- Do not forget to reinstall the purifier’s pre-filter.
- Do not assume the filter indicator resets automatically after replacement.
Replacement and Maintenance
Winix’s guidance for the corresponding Filter Q system is approximately 12 months for the HEPA and carbon stages, although the actual interval can change with your environment. A purifier exposed to frequent smoke, heavy dust or pet hair may load its filters faster.
Airflow is another useful clue. If the purifier has noticeably weaker airflow even after the pre-filter is cleaned, the replaceable filters may be heavily loaded.
The HEPA and activated-carbon stages should not be treated like the reusable pre-filter. Follow the replacement filter’s own care instructions rather than washing filter media that is intended to be replaced.
How It Performs in Real Use
For Everyday Dust and Pollen
In normal daily use, the HEPA layer provides the most direct benefit for airborne dust, pollen and other fine particles. Keeping the purifier running regularly gives it more opportunities to move room air through the filter.
For Homes With Pets
The combination of particle and carbon filtration can be useful around pets. The HEPA stage deals with airborne dander and fine debris, while activated carbon provides an additional stage for pet-related odors. You should still clean the purifier’s reusable pre-filter because larger hair can collect there first.
For Cooking and Smoke Odors
The activated-carbon layer can help with odors from cooking and smoke, while HEPA media captures many smoke particles. During heavy wildfire smoke or another serious air-quality event, however, a replacement filter should be viewed as one part of your indoor-air strategy rather than complete protection by itself.
For Long-Term Ownership
The 2+2 package is convenient if you intend to keep your 5510 or 5520 for more than one filter cycle. You can store the unused set until needed, provided you keep it clean, dry and protected in its packaging.
Compatibility and Safety
This is a replacement component for an electrical air purifier, so unplug the purifier before opening it for maintenance. Make sure the filter assembly sits correctly before closing the front panel and restoring power.
Do not modify or trim the filter to force it into another purifier. An incorrect fit can create gaps, interfere with the front panel or change airflow through the machine.
The filter also does not control indoor humidity. If your main problem is excess moisture, you need appropriate ventilation or a dehumidifier rather than expecting an air-purifier filter to lower relative humidity.
Pros and Cons
Pros
- Designed specifically around Winix 5510 and 5520 compatibility.
- Combines HEPA particle filtration with an activated-carbon odor stage.
- Package includes two HEPA and two carbon filters.
- HEPA media is marketed for 99.97% filtration down to 0.3 microns.
- Straightforward replacement process in compatible purifiers.
Cons
- It is an aftermarket compatible product rather than genuine Winix Filter Q.
- Compatibility is limited, so you need to verify your exact purifier model.
- Real replacement intervals can be shorter than 12 months in demanding environments.
Is It Worth the Price?
The value of this filter set depends mostly on whether you are comfortable choosing an aftermarket replacement. Because the package provides two HEPA filters and two activated-carbon filters, it may offer better convenience than buying one replacement pair at a time.
It is worth considering if you own a confirmed Winix 5510 or 5520 and want spare filters available for future maintenance. The main limitation is that you are not buying the genuine Winix Filter Q, so buyers who prioritize OEM filtration media may prefer the manufacturer’s replacement.
How It Compares to Alternatives
The clearest alternative is the genuine Winix Filter Q, part 1712-0123-00. That is the manufacturer’s specified replacement and is the safer choice if OEM status matters more to you than buying a third-party multi-pack.
Another aftermarket option is a BIHARNT-compatible 5510/5520 replacement set. As with this product, the main buying question is not simply which filter looks similar. Compare stated model compatibility, package contents and whether you prefer OEM or aftermarket filter media before deciding.
Frequently Asked Questions
Does this replacement filter fit the Winix 5510 and 5520?
Yes. This ASIN is marketed specifically as a compatible replacement for the Winix 5510 and 5520. Check the model label on your purifier before ordering because other Winix models can use different filter families.
Is this a genuine Winix Filter Q?
No. This product is sold as a third-party compatible replacement for Filter Q part 1712-0123-00. If you specifically want an OEM replacement, choose a genuine Winix Filter Q listing.
How many filters are included?
The listed configuration includes two HEPA filters and two activated-carbon filters. Check the selected Amazon variation before purchasing because package configurations can sometimes differ between listings or variations.
How often should the filters be replaced?
The corresponding Winix Filter Q system uses an approximate 12-month replacement interval for the HEPA and carbon stages. Your actual interval can vary with smoke, dust, pets, operating time and other indoor conditions.
Can this filter help with wildfire smoke?
The HEPA stage can capture fine smoke particles while activated carbon can help reduce some smoke-related odors. During serious wildfire conditions, follow local air-quality and public-health guidance rather than relying on an air purifier alone.
Does the filter reduce indoor humidity?
No. HEPA and activated-carbon filtration are intended for airborne particles and certain odors, not moisture removal. Use ventilation, air conditioning or a dehumidifier if excess humidity is the problem you need to solve.
What is the biggest mistake to avoid when buying this filter?
Do not assume every similar-looking Winix filter is interchangeable. Confirm that the label on your purifier says 5510 or 5520 and understand that this listing is an aftermarket replacement rather than an OEM Winix filter.
The Bottom Line
The 5510 5520 Replacement Filter Q Compatible Set is a practical option if you own one of the two listed Winix models and want a multi-pack containing both HEPA and activated-carbon replacement stages. Its main strengths are focused compatibility and the 2+2 package, while its main limitation is that it is a third-party compatible filter rather than genuine Winix Filter Q.
If OEM status matters most, choose the manufacturer’s Filter Q instead. If you are comfortable with an aftermarket replacement and have confirmed your purifier model, this set is worth considering.
