The PuroAir 100i HEPA Smart Air Purifier with Free Bonus Filter combines powerful performance with modern convenience, technology and style. Compact yet highly effective, it’s engineered to improve air quality in spaces up to 550 sq ft¹, making it perfect for bedrooms, offices, and living areas. With advanced filtration, the 100i helps remove airborne particles and odors1, creating a cleaner, healthier environment for the whole family. Its sleek design and portable build ensure that fresh air is always within reach, wherever you need it most.

At the heart of the PuroAir 100i is a powerful 3‑stage filtration system designed for cleaner, healthier air. The pre‑filter captures larger particles like dust3 and pet hair while extending the life of the filter. Next, the HEPA layer filters microscopic particles, and finally, the activated carbon filter reduces odors1, smoke1. Working together, these layers filter up to 99.9% of airborne particles as small as 0.1 microns³ including dust3, pollen4, pet dander4, smoke1, and allergens4. This advanced filtration process ensures that your home is filled with clean, healthy air.

Enhancing its performance, the PuroAir 100i delivers modern convenience with built‑in smart features. Connect the purifier to the PuroAir App via Wi‑Fi to monitor and control settings from anywhere, or pair it with Amazon Alexa and Google Assistant for effortless voice commands. To keep your air at its best, the 100i also sends filter notifications, ensuring clean, healthy air at all times.

Genuine PuroAir 100i Replacement Filters

For the best performance, always choose authentic PuroAir 100i HEPA replacement filters. Each filter is engineered specifically for the 100i purifier, ensuring a precise fit, smooth airflow, and proper seal integrity. With genuine PuroAir filters, your 100i delivers optimal HEPA and CarbonTech™ activated carbon performance to keep your home fresh and healthy.

What Makes PuroAir Filters Different

3-Layer Filtration System

Pre-Filter
Screens larger particles like dust³, pet hair, carpet fibers and lint.

HEPA Layer
Filters up to 99.9% of common indoor pollutants like pollen⁴, pet dander⁴, smoke⁴ particles, and fine dust³.

CarbonTech™ Activated Carbon
Helps reduce odors¹, smoke⁴ from cooking, pets, and cleaning products.

How Long Does a Filter Last?

For best results, replace your filter about every 90 days or 3 months. Regular replacement helps maintain:

  • Strong airflow
  • Peak purifier performance
  • Better odor¹ control
  • Consistent filtration efficiency

Usage, pets, smoke, and indoor air quality may shorten filter life.

Easy to Replace

Changing your 100i HEPA filter takes just minutes:

  1. Remove the old filter
  2. Discard the plastic bag from the genuine PuroAir 100i replacement filter and insert into the PuroAir 100i air purifier
  3. Reset your filter indicator (if applicable)

No washing. No mess. No complicated setup.

Not Washable

PuroAir filters are disposable by design. Washing can damage the HEPA and CarbonTech™ activated carbon filter media and reduce performance. Always replace instead of reusing.

Cost Per Month

Replacing your filter every 90 days helps break the cost into a simple monthly expense for cleaner air and better performance.

Why Choose Genuine PuroAir Filters vs. Knockoffs

Genuine PuroAir 100i Filters

  • Designed specifically for PuroAir 100i air purifiers
  • Proper seal for better airflow
  • Verified HEPA + carbon performance¹
  • Stronger odor¹ and smoke⁴ reduction
  • Built to last through the full replacement cycle

Generic Knockoffs

  • Poor fit may allow air bypass
  • Lower-grade materials
  • Weak carbon layers
  • Faster clogging or breakdown
  • Inconsistent results

A cheap generic filter can end up costing more by reducing airflow, weakening performance, straining your purifier, and needing to be replaced more often.

Keep Your PuroAir 100i Purifier Performing Its Best

Fresh filter. Strong airflow. Cleaner air. Choose genuine PuroAir 100i replacement filters.
