These are labeled as 25x25x2 replacements but the actual dimensions are 24.50 in x 24.50 in x 1.75 in, so measure the slot to confirm compatibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow often should these be replaced?\u003c\/strong\u003e\u003cbr\u003eAnswer. The manufacturer recommends replacing every 90 days under typical use, though homes with heavy pet dander or high dust may benefit from more frequent changes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these restrict airflow?\u003c\/strong\u003e\u003cbr\u003eAnswer. The MERV 11 media captures finer particles and may reduce airflow slightly in older or undersized HVAC systems; most modern systems handle them without issue, but check system compatibility if airflow is marginal.\u003c\/p\u003e","brand":"Filterbuy","offers":[{"title":"Default Title","offer_id":48610073149659,"sku":"B00CJZ9ERO","price":89.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/1043\/1707\/files\/717WFyNBIXL._AC_SL1500_6a3453c1-5377-4d50-b8c1-6484f0f54a8a.jpg?v=1778410883","url":"https:\/\/gearmusthave.com\/products\/25x25x2-air-filter-merv-11-superior-pet-allergy-defense-4-pack","provider":"GearMustHave","version":"1.0","type":"link"}
