Filtrete – Frequently Asked Questions
Filtrete is a brand of air filters manufactured by 3M, designed for use in home HVAC (heating, ventilation, and air conditioning) systems and as standalone air purifier filters. Here are 20 frequently asked questions about Filtrete:
- What are Filtrete air filters? Filtrete air filters are designed to capture airborne particles like dust, pollen, pet dander, mold spores, bacteria, and viruses as air passes through your HVAC system or air purifier.
- What types of filters does Filtrete offer? Filtrete offers a range of filters for furnaces, air conditioners, and standalone air purifiers, with varying levels of filtration efficiency and features like smart technology.
- What is MPR rating in Filtrete filters? MPR stands for Microparticle Performance Rating. It’s a 3M-specific rating that measures a filter’s ability to capture small airborne particles between 0.3 and 1 micron in size. Higher MPR indicates better capture of these tiny particles.
- How does MPR relate to MERV rating? MERV (Minimum Efficiency Reporting Value) is an industry-standard rating. While both measure particle capture, MPR focuses on smaller microparticles not always fully captured in lower MERV ratings. Filtrete often provides an approximate MERV equivalent for their MPR ratings.
- What MPR level should I choose? The ideal MPR depends on your needs. Higher MPR filters capture more allergens and smaller particles but can also restrict airflow more. Consider allergies, pets, and your HVAC system’s capabilities.
- Do Filtrete filters restrict airflow? While higher MPR filters can slightly reduce airflow compared to basic fiberglass filters, Filtrete designs its filters to balance filtration efficiency with optimal airflow when changed regularly.
- How often should I change my Filtrete filter? For 1-inch filters, the recommendation is typically every 90 days. However, this can vary based on usage, air quality, and filter type. Filtrete Smart Filters monitor filter life based on airflow and usage.
- What are Filtrete Smart Air Filters? Filtrete Smart Air Filters connect to your smartphone via Bluetooth and an app. They track filter life, provide outdoor air quality information, offer replacement reminders, and make reordering easy.
- Can Filtrete filters help with allergies? Yes, Filtrete offers filters specifically designed for allergen reduction, with higher MPR ratings to capture common household allergens like pollen, pet dander, and dust mite debris.
- Do Filtrete filters capture bacteria and viruses? Select high-MPR Filtrete filters are designed to capture microscopic particles, including bacteria and particles that can carry viruses. Check the product packaging for specific claims.
- Are Filtrete filters electrostatically charged? Yes, many Filtrete filters utilize an electrostatic charge to attract and capture airborne particles, acting like a magnet for microscopic allergens and pollutants.
- Can I wash and reuse a Filtrete filter? Most standard Filtrete HVAC filters are not designed to be washed and reused. Washing can damage the filter media and reduce its effectiveness. However, Filtrete now offers a refillable air filter kit with a reusable frame and replaceable filters.
- Does Filtrete offer refillable air filters? Yes, Filtrete has introduced a refillable air filter system featuring a reusable frame and collapsible, replaceable filter refills, aiming to reduce waste.
- Where can I buy Filtrete filters? Filtrete filters are widely available at home improvement stores, supermarkets, and online retailers.
- Are Filtrete filters more expensive than other brands? The price of Filtrete filters can vary depending on the type and MPR rating. Generally, they are positioned as a premium brand with advanced filtration technology.
- How do Filtrete filters compare to other brands? Filtrete is known for its MPR rating system and focus on capturing smaller particles. Comparisons often involve MERV ratings, airflow, and specific features like smart technology offered by different brands.
- What are Filtrete air purifier filters? Besides HVAC filters, Filtrete also makes replacement filters for their line of standalone air purifiers, designed with specific filtration levels for those devices.
- Do Filtrete air purifier filters use HEPA filtration? Some Filtrete air purifier filters are HEPA-type, meaning they capture a high percentage of airborne particles down to a very small size. Check the specifications of the specific air purifier filter.
- Where can I find the right size Filtrete filter for my HVAC system? The correct filter size is usually printed on the side of your current filter frame. Measure the length, width, and thickness to ensure you purchase the right replacement size.
- Does Filtrete offer filters for specific needs like odor reduction? Yes, Filtrete offers some filters with activated carbon layers designed to help reduce household odors in addition to particle filtration. Look for filters specifically labeled for odor reduction.
