What causes pet allergies?
Harmless proteins in pet dander, pet’s urine, saliva from your dogs/ cats could lead to pet allergies if you have over-sensitive immune systems. While pet hair is not part of the allergens, all the above allergens travels around pet hair and could cling on your cloths, sofa, wall and home for months if no action is taken. Symptoms for pet allergens include inflamed eyes, stuffy nose, itchy skin, wheezing, breathing issue and asthma. Another point worth mentioning is that pet allergies could come and go anytime while some owners would start developing pet allergies only after a certain stage of life.

Alen BreatheSmart might be featured in the list due to its best purifying performance and personalizable front covers, but to be more precise it's the odor neutralizer HEPA-OdorCell filter that won our heart. Unlike most air purifiers that comes with a standard set of filters, All Alen air purifiers has the option to select one of 4 HEPA filter based on your environment requirement ranging from HEPA-Pure (dust & allergens) to HEPA-FreshPlus (smoke & VOCs). For pets odors related issue, choose the HEPA-OdorCell filter filled with Alen's patented Molecular Conversion Powder that would destroy pet odors at a molecular level.
Again as each air purifiers has different set of functionality and price range, we recommend you to search for your most ideal Alen air purifier according to your needs and opt for the HEPA-OdorCell filter upgrade as it is best against pets odor.
Not the biggest tower air purifier in its class, GermGuardian AC5250PT is well-made and the only tower air purifier in the list that is super effective against pet dander yet would not take up much space. What makes it tick is a 4-stage filtration that includes permanent mesh filter plus charcoal pre-filter for pet odors, True HEPA Fresh filter for allergens, UV-C Light and GermGuardian special Pet Pure treatment that destroys airborne viruses, bacteria and germ. With plenty of filtration strength in its pocket, there is also a convenience 5 fanspeed and programmable timer for you to fiddle around with.
Its downside, average purifying coverage, slow airflow delivery rate and slightly over-bright indicator light that might annoy some. Overall we can't fault too much as GermGuardian AC5250PT holds it value well for a mid-range air purifier.
Austin Air Pet Machine is a very low annual cost maintenance air purifier particularly great against dog/ cat odors. Thanks to it specially impregnated Pet carbon/zeolite mixture carbon filter that is enhanced to tackle pet odors, the trio pre-filter (outer mesh, inner pre-filter and medium filter) would ensure no pet hair or other airborne particles would be able to leave the air purifier. Supporting all that is the final stage 60 sq.ft. True Medical Grade HEPA filter that would capture all micron-size particles mainly pet dander. Austin Air Pet Machine also has one of the widest purifying coverage (1500 sq. ft.) at 2 air released hourly; topping of all that is the super long-life all-in-one filter that could last up to 5 years thus the little maintenance needed.
What you will not get from this air purifier is Auto mode, air quality monitor/ sensor, timer or any modern features you could think of. Fan noise is louder than we prefer and it's also very bulky and heavy which is not great if you have very limited space. If you manage to bypass all that plus the price tag, Austin Air Pet Machine would be an excellent low-maintenance air purifier.

Small and cheap, Hamilton Beach TrueAir Compact Pet 04384 is a very specific, compact tabletop air purifier ideal if you have cats that often hang around your work desk. Cheapest air purifier in the list, Hamilton Beach TrueAir Compact Pet 04384 manage to squeeze in a permanent HEPA-grade filter in its small body and ensure your work desk stays free from pet hair and cat’s odor. On top of that there is also 2 carbon zeolite filters standing by to neutralize most common household allergens. Filter replacement cost is also very affordable and only require replacing quarterly.
The downside for such a compact air purifier is obviously its rather weak overall filtration performance. Purifying coverage is weak and limited, airflow delivery rate is poor which as the title suggested, is only good as tabletop/ addon air purifier on top of your main purifier.
Oldie but goodie, Winix 9500 Ultimate Pet PlasmaWave air purifier might be in the market for quite sometimes, it still possess the charm that most pet owner would be looking for. Powered by a 5-stage filtration that no doubt would trap any types of pet odors and allergies in its surrounding. The efficient pre-filter and True HEPA filter would stop cat hair, pet dander from flowing out while Coated Deodorization (CD) Carbon Filter would eliminate pet odor and other vapor based pollutants. Together with PlasmaWave Technology, there is also particle sensors, built-in timer, auto/ sleep mode and remote control to enhance on the air purifier usability.
On to the shortcomings, Winix 9500 Ultimate Pet design is clearly dated few years back, airflow purifying range is not great and rather low CADR compare with similar price range product. If you want the best in every aspect we should suggest you to consider the next product.
A better alternative to Winix 9500 in our book, Winix HR1000 is more competitively priced, better CADR, wider purifying coverage, airflow and with the same filtration efficiency against pet allergies. The washable pre-filter is great to clean up congested dust/ pet hair while CD Carbon Filter and True-HEPA filter is great in tackling pet dander and odors. In addition to that, Winix HR1000 also support WiFi control where you could pair up with your smartphone and remotely control literally everything on the air purifier.
Its not perfect though, Winix HR1000 annual filter replacement is slightly on high side and there is the minor indicator light glaring issue that might or might not be a big deal to you. If the WiFi enabled feature is not your thing, you could also opt for the non-WiFi version Winix HR950 that has the exact efficiency against pets allergens.
