Design and Build
The Wilerda 45321556-12010 Filter adopts a cylindrical 360-degree design that matches the original Clorox filter. Its outer layer is a pre-filter that captures larger particles like dust and pet hair, while the inner pleated HEPA and activated carbon layers handle finer pollutants and odors. The filter measures standard dimensions to slide directly into the Clorox 11010 and 11011 units without any modifications.
Each filter is constructed using FSC-certified paper, indicating that the material comes from responsibly managed forests. The overall build feels sturdy, with a dense pleat structure that suggests good particle retention. The two-pack ships in a compact box, and each filter is individually wrapped to keep it clean before installation.
Performance and Features
Three-Stage Filtration
The Wilerda filter uses a three-stage process common in modern air purifiers. The washable pre-filter traps dust, pollen, and pet dander. The true HEPA layer then captures airborne particles as small as 0.3 microns with high efficiency. Finally, the activated carbon layer absorbs volatile organic compounds and household odors (cooking smells, pet odors, smoke). This combination ensures that the air recirculated is noticeably cleaner.
Compatibility and Coverage
This filter is specifically designed for the Clorox 11010 and 11011 large-room air purifiers, which cover up to 1,500 square feet. It is not compatible with the newer Clorox 11030 and 11031 models, so owners must verify their machine model before ordering. The slide-in mounting makes installation straightforward, requiring no tools.
Indicator and Replacement Reminder
The Clorox purifier features a red filter light that illuminates after approximately 4,380 hours of use (roughly six months). At that point, it is time to check or replace the filter. Wilerda recommends replacing the filter every six to twelve months, depending on usage and air quality conditions.
Maintenance and Running Costs
Maintaining the Wilerda 45321556-12010 Filter is as simple as replacing the filter when the indicator light comes on. Because it is a disposable item, there is no need to wash or vacuum the HEPA or carbon layers. The pre-filter can be gently vacuumed or wiped to extend its life, but the manufacturer does not specify a washable pre-filter. The filter is made of FSC-certified paper, which is recyclable where facilities exist.
Since the package includes two filters, the replacement cost per filter is lower than buying OEM singles. While exact prices are not discussed here, many owners note in reviews that this two-pack offers good value compared to the original Clorox filters. The long replacement interval further reduces the annual upkeep effort.
What Owners Say
With an average rating of 4.7 out of 5 stars, the Wilerda 45321556-12010 Filter receives overwhelmingly positive feedback from verified purchasers. The majority of reviews rate it at five stars (83%), with another 12% giving four stars. Only a small fraction report issues (4% three stars, 1% one star).
Owners frequently highlight the easy replacement process and perfect fit. Many note that the filter traps dust, allergens, and pet hair effectively, and they observe an immediate improvement in air quality. Several reviewers mention that the price is great compared to the original Clorox filter and works just as well. A few customers had no problems and recommend the filter for its fit and performance. One minor complaint is that the filter is not compatible with newer models, so buyers must double-check their purifier model.
Pros and Cons
Pros
- Highly rated by verified buyers for performance and fit
- Cost-effective alternative to original Clorox filters
- Includes two filters in a single pack
- Features a three-stage HEPA filtration system (Pre-Filter, HEPA, Activated Carbon)
- Easy, tool-free installation process
- Made with FSC-certified paper

Who Should Buy It (and Who Should Skip It)
The Wilerda 45321556-12010 Filter is ideal for current owners of the Clorox 11010 or 11011 air purifier who want a reliable, budget-friendly replacement. If you prioritize keeping replacement costs low without sacrificing filtering capability, this two-pack is a smart choice. It also suits households that need to replace filters every six to twelve months and want a simple, no-fuss swap.
On the other hand, if you own the Clorox 11030 or 11031 models, this filter will not fit, so you should look for a compatible option. Additionally, if you require a filter with a higher carbon content for heavy odor removal, the integrated carbon layer in this model may be insufficient for your needs. In that case, a standalone carbon pre-filter or a different filter design might be more appropriate.
Final Verdict
The Wilerda 45321556-12010 Filter delivers on its promise of providing effective three-stage filtration at a competitive price. Designed specifically for Clorox 11010 and 11011 air purifiers, it fits perfectly, installs quickly, and earns high marks from owners for improving indoor air quality. The inclusion of two filters per pack adds convenience and value, especially when compared to buying single OEM replacements.
While the lack of compatibility with newer Clorox models is a limitation, for those with the correct purifier, this filter is a solid choice. Its strong owner ratings and straightforward maintenance make it a reliable addition to any home focusing on cleaner air. If you are in the market for a replacement filter for your Clorox large-room purifier, the Wilerda 45321556-12010 Filter is worth strong consideration.
