This filter is specifically designed to target, neutralize, and eliminate smoke particles and odorous compounds, providing you with cleaner, fresher air. The Smoke Clear Filter is more than 3 times more effective at removing chemicals from cigarettes and e-cigarettes from the air* than the original HEPA Filter.

By choosing our Smoke Clear(TM) HEPA Replacement Filter, you're taking the first step towards a cleaner, fresher, and healthier home. Our advanced HEPA (High-Efficiency Particulate Air) filter goes beyond ordinary filtration, capturing even the tiniest airborne particles like dust, pollen, pet dander, and mold spores. Its high-performance design ensures the trapping of 99.97% of particles as small as 0.1 microns, creating a cleaner living environment. *Initial efficiency value. As small as 0.1 microns from the air passing through the filter media. Additionally, the activated carbon filter possesses exceptional odor-absorbing properties, effectively reducing common household odors from cooking, smoking, and pets. Enjoy a space free from the discomfort of lingering smoke smells. Whether it's for your home or office, our SMOKE CLEAR™ HEPA Replacement Filter guarantees efficient elimination of smoke odors. With its easy installation process and long-lasting performance, our filter ensures that your air quality remains at its best. Designed for compatibility with [GermGuardian 22" Tower Air Purifier Series, our HEPA Filter Replacement offers easy installation and hassle-free maintenance. We recommend replacing the HEPA filter every 6 months to maintain optimal performance and efficiency.

Product Features

  • GENUINE HEPA SMOKE CLEAR™ REPLACEMENT FILTER: Our Smoke Clear™ HEPA Replacement Filter is designed to effectively combat smoke and fume odors. Whether you're dealing with the lingering scent of cigarette smoke, cooking odors, wildfire smoke, or car emissions, this filter's unique composition enables it to target and neutralize smoke particles and odorous compounds, providing you with cleaner, fresher air. Our HEPA filter offers exceptional efficiency in capturing up to 99.97% of harmful germs, dust, pollen, mold spores, and other allergens as small as 0.1 micron.

  • CERTIFIED EXTRA: With over 125 pleats and 8.0 square feet of filter media surface area, FLT4825SM SMOKE CLEAR(TM) filter is specifically treated to remove the particles, principal toxins, and some of the leading cause of cancer-causing gases found in cigarettes, e-cigarettes and wildfire smoke (Formaldehyde, Acetaldehyde, and Acrolein) and is OVER 3X MORE EFFECTIVE in removing those particles than the original HEPA Filter.

  • REDUCES ODORS: The activated carbon pre-filter and additional carbon embedded in the HEPA filter media increase the odor-removing power and reduces unwanted odors from wildfire smoke, cooking aromas, and gas stove, while also capturing large fibers, hair and particles. Indulge in your adventurous culinary creations without any concerns about lingering unpleasant odors.

  • PURER PARTS, PURER AIR: Genuine Germ Guardian replacement filters offer certified fit and maximum filtration. Off-brand filters often fail HEPA testing standards, fit incorrectly, reduce efficacy, and may cause damage to the air purifier.

Not satisfied with this dishonest Company

"I am not using the air purifier or the air filter, I did not want the air filter. But I had signed up for a subscription in error so it was sent to me without previous notice before shipping."

— Deborah W. (5/5)

"good filters at a decent price"

Product is great but support is really bad

"Shame on me I guess for making a mistake. On Wednesday at 5:30est P. M. I placed an order for these filters for the new home my spouse and I just purchased using the gaurdiantechnologies. com website. I realized when looking at the confirmation email that because of using google pay, it was being delivered to a house that was several years and many miles ago (don't know why that address is even listed as an option). Oops. Well at 7:30 P. M. (est) I filled out the "submit a request" form on the contact us page which included my name, email, and order number to cancel this order. At 8:21 AM the next morning I received a response via email stating they would be happy to cancel the order but would need my name, (wrongful) shipping address, email and phone number. I responded at 8:23 AM with the requested information. At 8:37AM I recieved an email stating that there had been a shipping label made at fedex but that fedex had not recieved the package. At 10:58 AM I received an email back stating "I was able to locate the order on my end, and after reviewing the status, it shows that the order has already been fulfilled. Because of this, it can no longer be canceled. I did attempt to cancel it, but our system wouldn't allow it. I hope for your understanding, you may chat with us at *insert website* we are available Mon-Fri 8am to 9pm". I went to the website to chat live so I could get this resolved (these are not cheap, I purchase multiple, and I would not be able to retrieve it from the wrong address) where I was met kindly but simply informed that I need to reach out to the carrier. I checked the fedex tracking again and they still had not received the package, so I asked that the issue be escalated because it was still in their possession, the agent told me "I cannot escalate this order because it has been fulfilled. please reach out to fedex to change the delivery address". Well, I went to fedex to try to change the address, but because I had opted for standard shipping, fedex informed me that service cannot be altered. I tried to reach out through the web chat again to see if they could assist me at all, and I was told "please check with us when the order is delived so we can help you in checking our available options". I asked they could pretend it was delivered, and simply inform me of the options, they said they would have to talk to a lead, I asked them to do that, they said they would and get back to me via email (convo ends at 11:53AM). At 11AM the day following I receive a follow-up telling me there is nothing to be done, I can try to contact the carrier to divert that package again (I tried, they wouldn't/couldn't). So, at this point I am out the money AND the product, and now know to double check the delivery address because Lasko product support cannot do anything to assist you if you are not talking to a human within 2 hours of ordering your product."

Hi I want to get replacement filters for two AC5350BCA units. Mfg Code 1752C Which of the current filters you are selling would be compatible? Please clarify if these are obsolete? My units work well and just need new filters. Thank you
Hi, Thank you for reaching out to Guardian technologies. We hope you are doing great! The compatible filter is FLT5000. We appreciate you as a customer and look forward to helping you in any way we can. If it is more convenient you may chat with us on Lasko.com . We are available to chat Monday through Friday from 8am to 9pm EST.
It says the carbon pre-filter can be "replaced every 2-3 months to extend the life of the HEPA filter." If the HEPA filter normally lasts 6 months without replacing the pre-filter, how long will the HEPA filter last if I DO replace the pre-filter every 3 months?
Hi, Thank you for reaching out to Guardian technologies. We hope you are doing great! The lifespan of the HEPA filter could last up to 6 months, but it depends on the usage how dirty the filter can be. Even if you don't change the pre filter but the indicator is blinking it means you need to change the filter. We appreciate you as a customer and look forward to helping you in any way we can. If it is more convenient you may chat with us on Lasko.com . We are available to chat Monday through Friday from 8am to 9pm EST.
