Key Differences Between the Brands

1. Filtration Technology:

Aerostar’s pleated air filters primarily employ electrostatic attraction. This mechanism involves using static electricity to attract and capture airborne particles, which helps in reducing common allergens such as pollen, dust, and mold.

On the other hand, Filtrete adopts a more advanced approach by merging electrostatic technology with specialized microscopic fibers.

This combination not only traps but also blocks a wider range of microscopic particles from the air, providing a more comprehensive filtration process.

2. Performance Levels:

Filtrete is known for its premium range, particularly high-efficiency filters boasting MERV (Minimum Efficiency Reporting Value) ratings exceeding 13.

These are particularly effective in capturing the smallest of particles, offering superior air quality. Aerostar, while also delivering reliable performance, reaches its peak efficiency at MERV 13.

This means that while they are effective, Aerostar might not be as efficient in extreme conditions as some of Filtrete’s premium models.

3. Media:

The media or the material used in the filter plays a vital role in determining its efficiency. Aerostar uses standard synthetic materials, which are effective for general-purpose filtration needs.

Conversely, Filtrete goes the extra mile by engineering their proprietary fiber blends, resulting in a more optimized and targeted filtration process suitable for specific environments.

4. Target Use:

While both brands cater to residential settings, Aerostar has expanded its reach to serve commercial sites as well, making it versatile in its applications.

Filtrete, keeping its focus narrow, primarily targets residential settings, ensuring a specialized product range tailored for home environments.

5. Availability:

When it comes to size versatility, Filtrete offers a broader spectrum. Their extensive size offerings mean homeowners are more likely to find a size that precisely fits their systems. In contrast, Aerostar provides fewer size options, which might limit the choices for some consumers.

6. Price:

Cost is a deciding factor for many buyers. In this arena, Filtrete’s filters come with a heftier price tag, reflecting their advanced technology and proprietary materials. Aerostar, providing effective filtration without the bells and whistles, offers a more budget-friendly alternative, making it an attractive option for those seeking value for money.

7. Lifespan:

Durability and maintenance frequency are crucial considerations for users. Filtrete’s high-end filters, designed with advanced materials and technology, can efficiently operate up to 12 months before necessitating a replacement.

Aerostar’s filters, being more affordable, have a shorter lifespan, usually between 1-3 months, implying a more frequent change is required to maintain optimal air quality.

Pros and Cons of Aerostar Filters

Some potential upsides and downsides of choosing Aerostar filters:


  • Inexpensive filters improve quality over bare minimum options
  • Electrostatic technology still captures many airborne particles
  • Suitable for residential HVAC systems and commercial buildings
  • Offer high MERV ratings up to 13 for decent efficiency
  • Durable construction for a 1-3 month lifespan


  • Limited size availability lacking for some HVAC systems
  • Filtration performance not as advanced as newer technologies
  • Short 1-3 month lifespan requires very frequent changes
  • Cheaper models may reduce system airflow
  • Not optimized for superior home air purification

Pros and Cons of Filtrete Filters

Some key advantages and potential drawbacks of using Filtrete air filters:


  • Extremely high filtration efficiency ratings up to MERV 15
  • Advanced dual-technology captures the full spectrum of particles
  • Highest-end filters filter out viruses, smoke, allergens, and more
  • Last up to 12 months for fewer filter changes
  • Significantly improve indoor residential air quality


  • Premium filters are far more expensive upfront
  • Advanced models can restrict HVAC system airflow
  • Most models only accommodated standard home sizes
  • Highest efficiency requires proper sizing and HVAC setup
  • Not cost-effective for commercial buildings

Cost Comparison of Aerostar Vs. Filtrete

On average, Filtrete filters are around 2-3 times more expensive than comparable Aerostar models:

Filter TypeAerostar PriceFiltrete Price
Basic Pleated$5-$10$10-$20
Mid-Grade Pleated$10-$15$25-$40
High-Efficiency Pleated$15-$20$40-$80
Maximum Efficiency PleatedN/A$80-$120

However, Filtrete filters maintain performance up to a year before needing replacement whereas cheaper Aerostar filters require replacement quarterly. This narrows the cost difference over time.

Overall Winner: Filtrete or Aerostar?

For pure air filtration at the lowest price point, Aerostar filters are the winner. But Filtrete air filters edge out Aerostar in terms of cutting-edge filtration performance, particularly their highest efficiency models above MERV 13.

Filtrete’s advanced media, pleating, and electrostatic microfibers significantly outperform Aerostar’s more conventional electrostatic filters when it comes to particle capture, airflow resistance, lifespan, and protecting indoor residential air quality against fine particulates.

For commercial buildings not requiring specialized performance, Aerostar’s affordability makes sense. But in residential settings, investing in premium Filtrete filters delivers superior air purification with less hassle from fewer filter changes.
